Saints Row 3 heat issue

I was wonder if anyone else has had GPU issues with SR3. Because for some reason this game is pushing my 560ti harder than BF3. In everyway; usage is 99%, temp 64c, and frames 30-45. In BF3 I get a constant 50-60fps and I usually bearly touch 60c with 99%. Im just wondering if im alone in this.

Try running it on 1 core only.

i had the same with bf3.

Old but I had to reply. WHY WOULD I DO THAT!?
