I've also noticed that the performace of the nVidia commercial driver stinks! I have a PCI Express 16X card with the Geforce FX 5300 chipset. In the past, it's proved to be very quick.......NOT now!! Below are my results with glxgears.......this is a P-4 3.2Ghz. box.
Yes, I read that. I also double checked to make sure my user ID is listed as "video" in the user setup, and it is. I get the same results you do.....not worth noting the difference.
Here too, with a GeForce FX 5200, and a P4 3 GHz, I get roughly 1000 FPS in the small window.
In full screen mode, 1600x1200 at 24bpp, glxgears gets reduced to 55 FPS! This seems to be awfully slow, or is this normal for that card?
Well - it doesn't look *too* bad. Though if you had higher performance in fullscreen windows before, this is a regression. glxgears is actually a valid indicator for fillrate issues, if used fullscreen. Just the higher fps numbers in windowed mode don't make any sense at all. At first I thought this is some change in optimization strategy (fps greater than 120 are nonsense), but given the number of reports I really think something is going very wrong in the driver. Someone please open a bug report and post the number of it here, so everybody who's seeing degrading performance (and also who isn't) can attach his numbers. All of those who add their data to the bug, please be sure to - check that 'glxinfo | grep direct' prints Yes - check that all device files /dev/nvi* are accessible (r/w) by the user - add information about + driver version (cat /proc/driver/nvidia/version) + graphics card (cat /proc/driver/nvidia/cards/0) + PCI-ID (lspci -n | grep 0300) + resolution and bpp + frame rates for glxgears in windowed *and* full screen + whether you notice jerkyness in any OpenGL applications + numbers from older drivers, if you still have them We will assign that bug to NVIDIA.
Would an update to the new 8776 driver version improve the performance?
Doubtfull.
