I need help with my GTX 570 and my Asus 27 led pb278q (2560 x 1440) !

Thread Starter 
Hi everyone,hope you are keen on helping me on this problem

Recently i bought a Asus 27 led pb278q (2560 x 1440) and I play left4dead on the highest setting on it

According to "precision X" my Gainward GTX 570 (golden sample)
was 99% being used and only managed to achieve 25fps on average ( with great lag )

Ok, but strange thing started to happen later, every now and then,it would show my GPU was only 50-70% used and
get 90 - 120fps ( very smooth )but normally, after the restart of the game or computer.I would get the same old bad fps and lag again...

And I pretty sure the setting was still on highest( i have checked it many times) and the graphic look pretty obvious

Does anyone here know how to get the problem fixed?

Btw, am playing on 2560 x 1440 and using HDmi 1.40a. if it matters

If there's a better section for this post please migrate it there

English isn't my native tonque, so please excuse for my mistakes

Thanks, looking forward for your help!

Probably down to the lack of vRAM for such a high resolution. You ant at least 2GB for that resolution gaming, anything under just doesn't cut the butter any more

for left4dead and left4dead2 that gpu should be plenty. I was able to run left4dead 1&2 at 1080p in SLI on 570s just fine....theres something a little off here...is this due to a crappy driver?
