ASUS Strix GeForce GTX 980 weird problem?

[OLD JUD]

Hi folks,

Just fitted a ASUS Strix GeForce GTX 980 4Gb graphics card today as an upgrade from a Gigabyte 7970, having a weird problem though......

Bench-marked the 7970 on War Thunder average of 116 frames, minimum 70.4.
Fitted the GTX 980 bench-marked at 211.3 average, 122.8 minimum.

Great i thought, then i had a session of War Thunder and part way through the game things got a little 'jerky' to say the least, frame rate dropped to the top teens low twenties.
I installed Asus GPU tweak 2, I manually overrode the fan settings in case it was getting too warm, to no effect. I tried the 'Gaming' setting this has no effect either, so at the moment the 7970 runs better.

I'm running Windows 10 (64bit) Nvidea 368.81 drivers if that's of any help?
It just seems that the card runs fast from booting up my PC then slows down as the card gets warmer?

** I've noticed that if I try to set 'Frame rate target' in GPU tweak regardless of what i set it to, either low frame rate or high, it immediately defaults to 50 frames a second **

Advice would be appreciated.

Run DDU (you can find on Guru3D) in safe mode, then reinstall the Nvidia drivers again, and see if that helps. Unless you did that already of course!

Hi thanks, uninstalled the ATI drivers with DDU in safe mode, used the option for fitting a new card, then installed the Nvidea drivers.

I'll try a re-install though.

Tried a re-install, it briefly increased framerate then frame rate dropped when I tried the 'Gamer' option in GPU tweak.

What PSU have you got driving it?

Are your other games playing as expected?

Is it set to Maximum Performance in Nvidia Control Panel? I haven't had great results with that new (default) Optimal setting.

Hi folks, thanks for the replies. I'm having problems with both my cards, actually, I think they are both alright but maybe the problem lies elsewhere.

I've posted another thread about that, any advice would be appreciated.
