3D programs on EEE PC 901 under Easy Peasy seem to run with unaccelerated video


I start GTAVC in wine, and it works _very_ slowly (about 3 FPS). I tried some tweaks for wine, and the result is that wine seems not to be the reason. lspci says that video card uses driver asus_eee.ko, while Xorg.0.log says intel driver is started (intel_drv.so). Having this, i suspect, that software rendering is used. How can i find out if it's true?

Edit:
Well, it seems that the driver enabled acceleration. But the performance is awful. What could be the reason? There are some videos of running GTAVC under windoze on the same netbook, and there it runs smoothly.
Here is my Xorg.0.log:

My guess is that lspci outputs the base driver used in console mode, while the X log outputs the intel driver used in X which DOES support acceleration.

You should search the web to find out if you can run GTAVC with wine. There usually are some tweaks that depend on the application that you try to run with wine (if it is possible to run the app at all).

You can try to enable Ubuntu's Desktop Effects to see hardware acceleration in action.

I found the reason for this, and, unfortunately it is not easily fixable. Intel drivers are based on Mesa3D project, which is very slow on most of the hardware, though faster than Mesa's software rendering. I checked X-Plane (it's cross-platform) in windows as well as in linux on the same intel graphics chip, and found that performance was the same. But that doesn't mean it's the fastest graphics operation possible for this chip. I tried GTAVC, and even GTASA on this chip under windows, and it worked perfectly. So, intel OpenGL support is much slower than DirectX support. I also tried GTA SA on nvidia card in both linux and windows, and in fact, under wine in linux it has better performance than in windows, so wine shouldn't be the reason of slowdown.
