Redraw/repaint problem with FX 5200 and OpenGL
Whenever I have an OpenGL app running (including GLXGears), certain screen redraw operations will be extremely slow. I can see the display redrawing line by line. This affects the entire screen including the non 3d parts. The 3D accelleration seems to work fine as I can rotate and interact with the 3D parts fine. During the redraw, the CPU untilization goes to 100% on both CPUs.
This is on a FX 5200 Ultra. I did not have this problem with a Geforce 2 GTS. It only happened when I installed the new card. I've tried both the 5328 and 4496 drivers on kernel 2.4.20-28.9smp. This Usenet thread seems to describe the same problem. Unfortunately, recompiling the kernel interface did not seem to help for me. |

I have the precise same problem on an XFX-brand GeforceFX 5200. I described the exact same symptoms in my thread here, which also got ignored.
Does anyone have any more information on this problem? If not, how can I help investigate it? [edit] Just realized something significant - we are both running dual processor machines. Has anyone had the same problem on single processor machines? Last edited by Corona688; 02-04-04 at 01:26 PM. |

Here is yet another ignored thread about an eerily similar-sounding problem with the FX5200:

I've managed to improve performance somewhat by setting Option "NvAGP" "1" in my XFree86 config file even though NvAGP doesn't support my motherboard chipset. It's by no means FIXED, however - the problem perists. I can now at least usually run XMMS and gears at the same time, but if I try and move any windows the jerking and lagging and such starts up again.

Let's see if we have any other configuration details in common:
Dual 1 GHz P3 Intel 840 Chipset eVGA Geforce FX 5200 Ultra Dell 1701FP connected via DVI /proc/driver/nvidia/agp/status reports AGPGART 4x Fastwrites and SBA disabled XFree86 4.3.0 The FX 5200 definitely seems to be common among all the threads I've found about this issue. |

I have hunted up my ancient Geforce2MX and am currently using it instead.
It works *fine*. The lag is gone. CPU usage no longer spikes up to 100% every couple seconds. It no longer bogs down into the strange state where CPU usage approaches 100% and sdlgears drops to <5FPS. In fact, I am currently typing in Konqueror, playing music in XMMS, scrolling text in a console window, and running sdlgears at the same time. This would have been unthinkable when using the graphically-superior FX5200. So it is pretty clear to me by this point that the nvidia Linux driver has serious issues with the GeforceFX5200. I would greatly appreciate a response from nvidia on this, any response at all. |
