I have a PC with Ubuntu10.04 and video card S3 VT8375 [ProSavage8
KM266/KL266] and I'm trying to run some 3D games with at least a
satisfactory performance, but I can not. I know that this chipset hasn't
a good 3D support in Linux, but I did a test with Linux Mint Debian
(LMDE) and the video came with a very acceptable performance, as this
comparison:
$ glxgears (On Ubuntu 10.04)
299 frames in 5.0 seconds
347 frames in 5.0 seconds
373 frames in 5.0 seconds
378 frames in 5.0 seconds
$ glxgears (On LMDE)
1249 frames in 5.0 seconds
1147 frames in 5.0 seconds
1107 frames in 5.0 seconds
1278 frames in 5.0 seconds
Furthermore, I discovered that Ubuntu doesn't use the correct driver for
the card for 3D acceleration and do insist on doing software
acceleration, which is slower than hardware acceleration:
$ glxinfo | grep render (On Ubuntu)
direct rendering: Yes
OpenGL renderer string: Software Rasterizer
$ glxinfo | grep render (On LMDE)
direct rendering: Yes
OpenGL renderer string: Mesa DRI ProSavageDDR 20061110 AGP 1x x86/MMX/SSE2
