Has anyone else seen this? OpenGL behavior is awful in Parallels 4.0. There was a definite regression. Parallels 3.0 did not suffer from this.
You can find out real easily by downloading and running the OpenGL Extensions Viewer at
http://www.realtech-vr.com/glview/ and running the "test" within the application. Note the reported (by the app) framerate is quite reasonable, but for some reason, the window isn't being refreshed often enough, so we get an apparent framerate of like 1fps. This happens with the sample OpenGL apps I have, as well as an app I'm developing, but running the OpenGL Extensions Viewer is the easiest way for someone to try to reproduce this slowness.
Sadly, this OpenGL extensions viewer actually crashes on the last few Parallels 3.0 builds. I was happy to see that it doesn't crash on Parallels 4.0, but alas the performance regression makes this build unusable for me.
I've filed a ticket #617802.
I should reiterate that the crippled OpenGL performance makes Parallels 4.0 completely useless for me. In fact, the reason I'm using Parallels, and not VMWare Fusion, is because of the OpenGL support. Without this, I've suddenly lost all reason to use this product.
Anyway, if anyone else is experiencing this, I'd be curious to know as well.
[EDIT] DirectX also seems to be broken in the exact same way. Is ANYONE here actually running any nontrivial graphical app with any degree of success? Anything I can download and try on my system to see if it's just me?
