Deus ex DX11 stuttering

[cleyndert]

Hi,

I am having problems playing Deus EX and shogun 2.

Hardware:
Intel i7 2600k
Gigabyte Nvidia GTX 560 ti
16gb ram
120gb ssd(30gb free)
samsung 60" plasma
asus p8z68-v pro gen3

Software:
Steam
Windows 7
fraps
cpuid
windows security essentials


Problem: The game initially plays well. Within a couple of minutes fraps shows 9. If I tab in and out, it runs again. It doesn’t matter what setting a downgrade to, it continues to slow down. If I downgrade to dx9, everything is great. Trying to figure out what is wrong. Please help.
I had a problem with shogun, but a little different. With shogun, the game wouldn’t fit my screen. It didn’t matter what resolution I chose. Once again downgrading to dx9 fixed the problem.

seen a few people with nvidia 5 series cards saying they couldnt play deus ex properly on dx11 unless they upped the voltage

on their card

just google --deus ex dx11 voltage--and you should find results

Thanks for the reply. This Hasn't fixed the problem. I had the voltage up to 1075. From what i was reading in the voltage posts, was the game was crashing. My game isnt crashing. It just slows down to annoying speed.

Do you have any other suggestion?

Oh, when I looked at cpuid, temperatures were normal.
