I have a desktop that I use for gaming. The specs are at the bottom. I bought my computer originally, but since then I've upgraded it a lot. Other than the case, hard drive, and some wiring.

As I said this is a gaming desktop so how come I can run GTA V at about 10-15 fps at lowest settings, while my friend who has a computer slightly better, still run the game at about 70 fps on highest settings? Not to mention I only average to 120 fps on CS:GO with no fps limit, while the same friend runs it at about 400 fps.

His build is only slightly better. His having a six-core AMD processor. Also if I'm playing anything and try to load Google Chrome it takes ages. In my BIOS it says I have 4 cores but everywhere else says I have 1 core and 1 logical processor.

I understand that BIOS is the absolute final word, and everything saying that I only have 1 core doesn't bother me. It's just that my processor is performing a lot worse than it should be. Every time I open Skype my processor usage shoots to about 80%. My friend has the same amount of RAM except his is DDR3.

    Dxdaig logs please. GTA is CPU intensive, verify Hyberthreadinng is enabled – Ramhound Mar 1 '16 at 22:18
  • Press Control + Shift + Escape. From there go to the performance tab, right click on the CPU graph, and choose "Change graph -> Logical Processors." Verify that you have four cores and post what it is. – headkase Mar 2 '16 at 21:59
  • Scratch my post: I see you are showing 1 core. Did you modify your environment variables? One of them is the number of cores Windows thinks should be there. Right click your Start button, choose System, click on Advanced System Settings, click on Environment Variables, under System Variables post the contents of Number of Processors. – headkase Mar 2 '16 at 22:03
  • There should be eight logical processors. The OP has an i7-6700K, which is a 4C/8T part and should appear to the system as having eight processors. – bwDraco Mar 2 '16 at 22:03
  • It's best to use Imgur to post your images; see the bottom of superuser.com/help/formatting for details. (If this isn't convenient for you, which may sometimes be the case, please let us know.) – bwDraco Mar 2 '16 at 22:04

It sounds like you need to enable multiple cores in Windows 10 Windows X, Run, msconfig, Boot Tab, Advanced Options, Tick number of Processors and select the correct number of cores, and restart Windows.

You should also check your system for Malware and Virii.

  • It's not that. I just looked and there's only one option. And that option is 1 core. BIOS is the only thing on my entire computer that says I have 4 cores. I hope this was some help to you. If you come up with another possible fix, please tell me. – NeverTrustNanners Mar 1 '16 at 23:38

    Please provide a screenshot, of what you see, and of task manager. Go ahead and also provide that dxdiag report.. – Ramhound Mar 2 '16 at 3:33

I have reinstalled Windows 10 and I now have all 4 cores working and Windows is detecting 8 cores like it should. The problem was that I upgraded my processor and it didn't recognize it. I put this problem on 3 different forums. And thank everyone who helped me out.
