Poor performance for full-screen flash, geForce 8200

If I've misunderstod please don't hesitate to explain with small words (No sarcasm, I am new to this level of digging into unix, so I very often don't catch everything).

The curious differences (that I see so far) are that I don't have any sound in 173, but good video, and someone else pointed out (I still need to verify on my system) that in 173, both cores in the proc are used, but 177 and 180 only load down 1 core.

Thanks,

x86 does mean both 64bit and 32bit. He was talking about PAT, you can disable that in your kernel configuration or by passing nopat to the kernel.

The thread that you linked to shows that the 64 bit kernel of ubuntu intrepid doesn't have PAT enabled, that's why zim2dive said he has tried both with no difference. Also the PAT issues effected the 173 drivers as well, so it would be strange that 173 would be fine but 177 would not, if the problem was related to PAT.

OK, btw I never had any PAT issues on both AMD and INTEL systems.

(I did not link to the thread, SlowPerson did )

Yes, thanks, that is what I was trying to say.. although I wasn't certain I fully understood it all

If its activated try adding nopat to your grub kernel.
Afaik it is activated by default on x86 kernels..

Btw first post - Hi everyone!

~$ grep X86_PAT /boot/config-2.6.27-7-generic
# CONFIG_X86_PAT is not set

It was already off for me..

I didn;t try 180.22 yet, but I can confirm that 180.18 does nothing to help full-screen flash on the 8200.. still chokes and dies on The Daily show and hulu HD (reverting to 173 fixes performance)

Don't waste your time. I just tried 180.22 on the off chance that nVidia had actually fixed something, but it is the same old story for use 8200 owners. Crappy 2d performance, and unbearable flash performance. I'm beginning to wonder if they purposely ignore our cries for help...

There is a definite (and disappointing) lack of acknowlegement from the nVidia side with regard to this issue.

I will check the new driver on the geForce8200

seems to be an issue with 8200

I just replaced my old geforce 6100 + sempron3000+ with an dual core athlon and 8200
and i was shocked at the youtube performance under my new box (just switched the hdd to the new one)

Some more info on the problem, it seems to be more a firefox and nvidia series 177 180 driver problem. I installed 1.63 opera, and flash performance is much much better, and youtube works better than in firefox.

There are also other problems when running firefox and 177 and 180 drivers including 180.22. If firefox has the focus and you select a menu on another app, it is slow to respond. also if firefox has the focus and one hits alt-f2 for run, it is slow to repsond, also compiz effects can sometimes be slow if firefox had focus last and you say close a different app. These problems don't happen if other apps(both gnome or non-gnome) have focus.

I am running 8.10 Ubuntu with 8300 mGPU, and firefox 3.0.5. all problems are with or without compiz.

The problems don't occur with firefox and 173 drivers, but 173 with compiz causes corruptions sometimes in firefox with scrolling.

My next experiment is to try firefox 3.1 beta2, to see what happens.

there's a problem also in flash player.
if you right click on any flash content, under "settings", you can see "hardware acceleration" turned on: disabling for me solved any lagginess in flash content.

This has no effect for me, performance and cpu % are the same either way, both in firefox and Opera.

Are you using a 8300/8200 ?

Also, I'm running 64 bit Ubuntu with the 64 bit flash alpha release. I had the 32 bit flash with wrapper earlier and it didn't perform any differently with 173 177 or 180 than 64 bit flash, I believe I tried unselecting hardware acceleration under 32 bit flash with no effect also.
