bjoure Posted August 25, 2010 Share Posted August 25, 2010 So,,,, I downloaded a pre-made Snow Leopard VM (10.6.2) and run it in my VM Workstation 7, and it works surprisingly well, and pretty fast too. Sound and network are both working, and I have no problem with fullscreen resolution. However, graphic performance is painfully slow. Basically everything that utilize GPU is jerky. Fullscreen youtube video is unwatchable too. I am running the VM machine on i7 920, 6GB RAM and ATI 4870. I have given SL 4 cores and 4GB RAM. Geekbench score is 8900. But still. I understand it's because my GPU isn't recognized at all in this SL VM. Currently in System Profile my 4870 is listed just as GPU with 128MB VRAM on a PCI bus. So the lack of Quatez Extreme and Core Image is probably the culprit of slow graphic performance I guess? Can I install SL anew to solve this? I don't really care if I use vanilla kernel or not since I don't care about software updates etc. So can customized ATI kext help? All I want is better 2D performance so the Snow Leopard UI is smooth, not 3D performance. Link to comment Share on other sites More sharing options...

VMware uses a virtualized GPU called VMware SVGAII, and does not use the native card. Also there are no 3D accelerated drivers for it. Link to comment Share on other sites More sharing options...

Ok found the driver on the next thread. 2D performance is much better. But I still cannot play video properly. VLC doesn't give me any video when I play one, but audio is perfect. Any thought? Is it because VLC now support hardware accelerated video decoding? Link to comment Share on other sites More sharing options...

The driver you loaded is not going to be developed to handle other acceleration. Link to comment Share on other sites More sharing options...
