OS X :: SL Performance Drop In OpenGL In Spaces?

Sep 3, 2009

After upgrading to Snow Leopard on my brand new MBP, I have taken notice of a definitive perf drop in OpenGL, particularly when I make use of switching windows via Spaces. The transition between windows skips and is not a smooth animation.

Mac Pro :: How To Get Better Performance With OpenGL

Jul 14, 2010

So I just installed the Apple ATI Radeon HD 4870 in my 2.66 quad Mac Pro1 1. Everything seems to be great but when I ran Cinebench I noticed that it is running OpenGL Engine, 2.0 ATI-1.5.48. In the results I see another 4870 with higher scores running OpenGL Engine, 2.1 ATI-1.6.6. My question is this. Is there something I should update for better performance? Is this a difference in cards, OS, drivers, firmware?

OS X :: OpenGL Graphics Performance In 10.5.6

Dec 16, 2008

I just noticed that Xbench gave me a better OpenGL score on my new late 2008 MacBook compared to 10.5.5, so I was wondering if anybody knows how much better the graphics performance actually is in 10.5.6? Although I just traded in my old white MacBook with a crappy intel graphics card for the new MacBook with a rockin' graphics card, I am curious how much the 10.5.6 update improves performance on the intel graphics cards. Can anybody compare the OpenGL results from 10.5.5 and 10.5.6 to see if I'm the only one who is seeing an improvement. Did Apple update the graphics card drivers or is there some other reason I'm seeing better performance?

Mac Mini :: 3.1 (2009) - OpenGL Performance 2x Slower Than 2.1

Apr 4, 2009

I've noticed something rather subtle at first. My new mac mini just did not give me any faster feel comparing to old one, as matter of fact my old mini seamed faster and smoother. After comparing minimize/maximize animations while holding shift on old and new system system by side, I have noticed that new one gives off as having 2 times slower frame rate or slight flickering when doing minimize, maximize and magnify effects on dock. Also gave some shabby feel comparing to old one.

After I have run XBench of both systems and 2 restarts, it came as consistent result that new system scored 125+/-4 vs old one 280 on OpenGL test, more than 2 times slower! I expected upgrade to be upgrade, not downgrade! What could be issue, it is supposed to be 5 times faster. Is it not tuned up or quite not ready drivers. Will this issue be fixed by apple anytime soon? I love apple but I feel disappointed that my old system gives smother user experience than my new one.

Mac Pro :: Graphics Drivers And DirectX - OpenGL Performance

May 5, 2010

This seemed like the most logical place to ask this, since the Mac Pro forum seems to be where all the higher level hardware/software modification discussion is. Currently the Starcraft 2 beta is suffering from horrible performance problems. Many of the threads I've read on their support forums point to graphics drivers as the main culprit, with DirectX->OpenGL porting being close behind. The main problem with both seems to be shaders.

One thread I found, however, is in reference to performance on Hackintosh machines. Apparently Hackintosh users, who all use custom graphics drivers for specific graphics cards (ones not ever supported by OS X, like the GeForce 9800) are getting performance on par with boot camp users, at similar settings. So my question is this: is it possible to write custom graphics card drivers for normal mac users (I myself use a flashed 4870) that optimize the use of extensions for shader intensive games like SC2? If so, where should I start looking to figure out how?

MacBook Air :: 10.6.3 - Huge Graphics Performance Update To OpenGL?

Mar 30, 2010

I have been reading that several people are seeing much cooler temperatures on their Mac notebooks and they think it's due to better graphics drivers with the update to 10.6.3. I however thought about the huge performance hit in OpenGL going from Leopard to Snow Leopard (probably same thing). So I decided to check my OpenGL results after installing 10.6.3. However, I didn't check my xBench results before upgrading to 10.6.3. I went and found an old result which shows 67 points for "OpenGL Graphics Test." My new result for "OpenGL Graphics Test" is 111 points. When I check the xBench archives, people with rev "C" MBA's with 10.6.2 all show OpenGL Graphics Test scores in the 60s.

If this is correct, we could all have some big improvements that really show huge effects on the MBA. It should help everyone running Snow Leopard. It should lead to graphics performance gains and lower heat due to graphics demands. Could someone else running 10.6.2 on a 2.13 GHz CPU MBA run an xBench test before the 10.6.3 upgrade? Then upgrade to 10.6.3 and run another xBench test. Then please report back here with your results for OpenGL Graphics Test and hope this result is great for all of us. I believe this would be a big improvement for the original MBA too?

Mac Mini :: Video Performance - Remarkable Slow Score On OpenGL

Jan 24, 2010

I just got a brand new Mac Mini 2,26 Ghz Core 2 Duo, 2 gig RAM, and it's hooked up to my tv with a mini-DVI adapter. Snow Leopard installed. I noticed right away that the screen looks really sluggish, with screen tearing and laggy video performance. Playing videos in Plex for instance there is a lot of screen tear and I had to set the display to 720p to get it decent, and even then it's rough, even on SD videos! So I ran Xbench, and got a remarkable slow score on OpenGL; 43. My MacBook Pro running with the 9400M card got 97.

OS X :: Slow Graphics Performance When Using SL Expose And Spaces

Aug 29, 2009

I am seeing very slow performance when using spaces and expose in 10.6. I am on a mac mini with the 9400m graphics chip. It worked perfectly in Leopard, and now it runs at what appears to be 1fps. Sometimes it doesn't even seem to animate, it just jerks into place, from starting point to the end. I realize one solution could be "do a fresh install" but that seems like quite the pain at the moment, and is extremely undesirable. The upgrade worked perfectly on my macbook pro with similar specs. Is there anything I can reset or reinstall that might refresh the graphics performance?

OS X :: Increasing Number Of Default Spaces Decreases Performance?

Jan 1, 2010

I use Spaces all the time when running my mac. I like applications having a dedicated space so I can leave many open at once without losing screen real estate. I just discovered that in the Preferences you can increase from the default 4 spaces to any number you want. If I increase this number will I start noticing performance decreases? I realize if I leave too many apps open I may notice it, but assuming I have the same number of apps running, will I see the same performance if I have 6 or 9 (or more) spaces open as if I only had the default 4?

MacBook Pro :: 10.6.5 Update Drop Gaming Performance?

Dec 10, 2010

MBP 2.4ghz (MBP4,1)
4gb ram, geforce 8600m gt

Before the update I was gaming perfectly fine on pretty much Medium - High settings. The only game I have been playing lately is HON - Heroes of Newerth. Everything ran exactly as it should and I never had any problems. However, a couple of days ago I booted up the game and tried to play and noticed my FPS dropped by a lot. I even tried cranking down everything to low, and all it does is make everything pixelated, but my fps does not move at all.

I then realized the day before, I ran Software Update and ended up bumping up to 10.6.5. I honestly cannot think of what other reason in why performance would drop. I ran both a disk permission repair and a verify disk repair. Ran onyx to do a clean up scan. Flash online, video files, music, everything else I have tested is performing as it should. Anyone else having issues with the recent osx patch?

MacBook Pro :: Major Drop In Video Performance With 128 GB SSD

Aug 23, 2009

I've had my brand new 13" MBP with 128GB SSD for a month or so and love it. However in the last day, performance has dropped dramatically while watching video. I was on Hulu watching a high-res show, and about 15 minutes in, it started getting very choppy -- audio was OK, but video performance dropped. I quit, restarted, tried again, same problem immediately. System load was around 2.79. I tried in both Safari and Firefox, no dice. YouTube seems to have dropped now as well (I'm playing a video in another tab now, and again the audio is great but the video is choppy). I'm currently hooked up to a 22" LCD through the DVI output (the laptop itself is closed).

Is this normal? I mean I've got 4GB of RAM and 2.53GHz CPU with a solid-state disk! There should be 0 latency and this dual-core beast should tear through video no problem, and here I am closing off iTunes and other apps to try to spare some CPU (this doesn't work though). I've even switched to standard-res for both hulu and youtube but it's not much better. I am shocked that a brand new 2.53GHz CPU with 4GB can't handle this. I also installed and am now running Hulu Desktop to try to get better performance. The really weird thing is a week ago I was a on a flight chewing through YouTube while on Skype and using Entourage and iTunes all at the same time, and it was blazing fast. Now I'm crawling along like an old 1.6GHz with 512MB RAM. WTF, mate?

MacBook Air :: 10.7.4 Caused Massive Performance Drop

May 11, 2012

Since updating, my computer is barely usable. Geekbench score fell from ~5400 to ~ 2300, so it's not just my imagination. I was exporting video and the processor didn't even feel warm, but Activity Monitor reported that it was giving it all the power it had. Anybody else seen this? I'm on a 13" mid 2011 Air with the i7 nad 256GB SSD.

MacBook :: Sudden Drop In Performance After CD Import Failure

Jul 27, 2010

My macbook was running at basic, normal speed, nothing too serious for a year-old laptop, but suddenly one day, my performance dropped sharply, to the point where it would take up to ten minutes to attempt to get to a page, and songs would freeze for about a minute about 3 times per song in iTunes. It all started when I attempted to import a CD into iTunes (it was downloaded onto my HD, not imported directly from a CD), and I got the message "attempting to copy to the disk macintosh hd failed. The disk could not be read from or written to." About this time, my computer started acting unusually slow, (the problems mentioned above).

I did some looking into this, and did both suggestions listed here (Disk permission repair, then manual iTunes folder permissions change):
After this my problems were eased for a little bit, I was even able to import the folder I had been unable to import earlier. But I tried then to import the very next CD (it was an 8-CD set), and then I got the same error. Thinking it was possibly a problem with a corrupted/infected file, so I ran a scan through my whole computer (using McAfee), which didn't return any problems. Then, on top of this, my mac suddenly stopped burning CDs, saying that the CD failed because of a "medium write error."

OS X :: OpenCL And OpenGL Take On DirectX

Dec 16, 2008

The broad industry support Apple is building around OpenCL will help increase the critical mass behind OpenGL, the 2D and 3D graphics language Apple uses extensively in Mac OS X. Since the mid 90s, Microsoft has worked to prevent the adoption of OpenGL as an interoperable industry standard in favor of its own proprietary DirectX portfolio of graphics software and gaming tools.

OS X :: Easy Way To Upgrade To OpenGL 3.1?

According to System Profiler I have OpenGL version 1.5.10 installed on OS X. Is there a way to easily update this like with Direct X on Windows? I play some Diablo II which is a Mac game and it looks a bit more washed out than how it appears in Windows; wondering if an OpenGL update might help. It's up to 3.1 now.

OS X :: 10.6.4, OpenGL, Blizzard/Valve

May 19, 2010

With the recent release of Steam for Mac, and the countdown to the release of Starcraft 2, I've been thinking that Blizzard and Valve should (or current are) actively pursuing Apple to make OS X more compliant with OpenGL, and at the same time increase effieciency of their graphics card drivers. Both of these companies are having the potential market for Mac gaming grow every day, and need their clients to run as smooth on a Mac as they would on a PC. I followed the dev builds of 10.6.3 somewhat closely, and remember seeing the builds add in compliance with OpenGL 3(?), so my question I'm asking is: Do you think Blizzard and Valve are actively working with Apple to increase performance for their games?

OS X :: Khronos Announces The OpenGL 3.3/4.0 Specifications?

Mar 11, 2010



OpenGL 4.0 further improves the close interoperability with OpenCL™ for accelerating computationally intensive visual applications. OpenGL 4.0 also continues support for both the Core and Compatibility profiles first introduced with OpenGL 3.2, enabling developers to use a streamlined API or retain backwards compatibility for existing OpenGL code, depending on their market needs.
OpenGL 4.0 has been specifically designed to bring significant benefits to application developers, including:

two new shader stages that enable the GPU to offload geometry tessellation from the CPU;

per-sample fragment shaders and programmable fragment shader input positions for increased rendering quality and anti-aliasing flexibility;
drawing of data generated by OpenGL, or external APIs such as OpenCL, without CPU intervention;

shader subroutines for significantly increased programming flexibility;
separation of texture state and texture data through the addition of a new object type called sampler objects;

64-bit double precision floating point shader operations and inputs/outputs for increased rendering accuracy and quality;

performance improvements, including instanced geometry shaders, instanced arrays, and a new timer query.

Lastly, Khronos has simultaneously released an OpenGL 3.3 specification, together with a set of ARB extensions, to enable as much OpenGL 4.0 functionality as possible on previous generation GPU hardware; providing maximum flexibility and platform coverage for application developers. The full OpenGL 3.3 specification is also available for immediate download at [URL]

"The release of OpenGL 4.0 is a major step forward in bringing state-of-the-art functionality to cross-platform graphics acceleration, and strengthens OpenGL's leadership position as the epicenter of 3D graphics on the web, on mobile devices as well as on the desktop," said Barthold Lichtenbelt, OpenGL ARB working group chair and senior manager Core OpenGL at NVIDIA. "NVIDIA is pleased to announce that its upcoming Fermi-based graphics accelerators will fully support OpenGL 4.0 at launch."

"AMD sees the release of OpenGL 4.0 as another major accomplishment for the OpenGL ARB," said Ben Bar-Haim, vice president of design engineering at AMD. "AMD contributes to the Khronos workgroups, and we consistently find that Khronos is successful at developing healthy, thriving, and evolving open standards such as OpenGL and OpenCL."

"OpenGL 4.0 continues the ARB's schedule-driven roll-out of new functionality, and this significant major release enables developers to access leading-edge GPU functionality across multiple platforms with full backwards compatibility," said Neil Trevett, president of the Khronos Group and vice president at NVIDIA. "OpenGL continues to be a keystone in the Khronos API ecosystem, through driving innovation into OpenGL ES and WebGL™ to bring high-performance programmable graphics to mobile platforms and the Web, and by interoperating with OpenCL to create a seamless visual and compute platform for application developers."

Applications :: Photoshop CS4 - OpenGL Disabled?

Mar 2, 2009

I have a 2006 MBP 2.2Ghz with 128mb Nvidia 8600M graphics card. I installed a trial version of Photoshop CS4 back in November, and was able to use the OpenGL effects of zooming in and drift-moving the canvas around. However, having installed the full version earlier last month, I've noticed none of these features are enabled, and in Photoshop's preferences it claims I need a new video card or driver. My drivers should be up-to-date, as I've installed all Apple's firmware and software upgrades via autoupdate.

OS X V10.7 Lion :: How To Get Back OpenGL After XQuartz Install

Jun 3, 2012

I wanted to play around with GIMP, so I downloaded it and it told me that I must have xQuartz installed. I installed it and it apparently damaged my OpenGL engine. Now when I open Photoshop psd files with 3D effects, I get the following dialog box: 

I have to assume that it is xQuartz that did the dirty deed. 

I Googled but could not find a way to delete it ad get back to X11 (and, hopefully, OpenGL). I could always do a restore from an older Time Machine back-up, I know, but I'd lose a lot. And I don't really remember when I installed it - last week sometime.
