8800 gtx _very_ slow in 2d apps

[Cadynum]

Hi, my 8800 gtx is performing very bad at 2d applications.

Examples:
Scrolling in Firefox is very slow.
Using Inkscape or Gimp results in 100% cpu when just moving around simple graphics.
Using 2d app x and doing simple task y -> 100% cpu

The 3d acceleration is working fine though.
I have tried every available driver that works with 8800 gtx (including the new beta), Xorg 7.1 and 7.2 , kernels 2.6.(16 & 17 & 19 & 20 & 21)

System:
Gentoo amd64 (have tried with Ubuntu amd64, same problem)
Evga 680i
Core 2 Duo e6600
Gainward 8800 gtx

Attaching nvidia-bug-report.log. Look at the "cat /proc/mtrr" - it doesn't look very good

Another thing that doesn't work properly is cpu interrupts, ("cat /proc/interrupts"). I doubt it has anything to do with the gfx-card. But if anyone know the solution I would be glad to hear it.

If anyone have the solution to this I will be forever thankful!

I'm not happy with the 2D performance of mine either on Ubuntu feisty. My 7800GTX was much faster. My work computer is running Ubuntu Dapper with a 7900GS and it's faster

Yeah, very, very annoying.

sorry, double.

Same problem but with a ti4200.

No resolution in site, have tried many drivers.

Resizing windows = video lag
Minimizing / maximizing windows = video lag

This is a NVIDIA problem.
