Keep getting windows message when running AC

[bsmooth]

I'm running AC and since I have , once in awhile I get a message:
"Windows has detected that your performance is low. Do you want to change the color scheme to improve performance ?"
I'm getting steady 48 - 80's FPS, and the game seems to run very well. My system isn't top notch and is several years old now, but it had very good components at the time,system as follows:
Win 7 64 bit
MB ASROCK|P67 EXTREME4 (B3) P67
VGA ASUS|ENGTX560 TI DCII TOP/2DI/1
MEM 4Gx2|KST KHX1600C9D3K2/8GX
CPU INTEL|CORE I5 2500K 3.3G 6M
HD 500G|SEAGATE ST3500514NS
As I said it runs fine for me, is theres some tests I could do, to find out why I'm getting the message and how it can be fixed, or If anything actually has to be done at all ? Thanks
