Worse performance after CPU upgrade

System Specs :
GPU : EVGA NVIDIA GTX 950 SSC
CPU : Old - i5 3570 New - i7 3770k
Motherboard : ASUS P8Z77-V-LX
RAM : 8GB of DDR3
OS : Win10

After installing the new CPU, I launched up CS:GO and was only getting 30-60fps. With my old i5 i would be getting around 120-150fps.

I checked to make sure that the BIOS I had was compatable, and it was. Also ensured my graphics card drivers were up to date, and everything seemed fine.

I checked other games and in Don't Starve i was getting 30fps, compared to a solid 60fps before, and also around 40fps in Far Cry 3 instead of a solid 60+fps.

It's also worth mentioning that after trying to troubleshoot for a while and failing, i left CSGO running in the background for 45 mins, and when i came back it was running at 250fps like i would expect, but after restarting the game it went back down to what it was before.

I've checked to make sure that the settings for the BIOS are correct, ensuring that it wasnt on power saving mode and what have you, but everything looked fine. Any ideas?
 
If you reset the BIOS to default settings does that help?

Also to double check, your BIOS version is greater than or equal to version: 0312?
It may be worthwhile to update to the latest 2501 BIOS if you aren't there already.

Also read through the OCIng guide for it, even if you aren't OCing, because it's OCable, you may need to enable/disable a few motherboard features to get it to work right: http://www.tomshardware.com/forum/279408-29-bridge-overclocking-guide-3770k

Just reset to the default BIOS settings, no improvement. The bios version is 1106 so its well in the accepted range, and i don't particularly want to flash it if there isnt any purpose. As to that overclocking guide, where exactly do i begin with it? im kind of lost as to how that would help me.

Yes, thanks so much! the frames are now at around 250-400 :D any reason why this fixes the issue?
 
Wow I can't believe that fixed it!! I was just thinking logically that your went from an I5 to an i7 and that the only change was really hyper threading. Just remember you may have to re-enable hyper threading when you play more cpu intensive games for better performance. This is most likely the game optimization and that it's seeing two logical threads as two physical cores. So when you disabled hyper threading, you went from using one core with two threads, to using two actual cores.
