Hi, when I'm playing Rainbow Six Siege, my CPU usage is constantly 85-100% and It's making the game unplayable due to lag. I've tried messing with video settings but no luck.

CPU: Fx6300
GPU: EVGA GTX 1060
RAM: 2x 4gb G.skill Ripjaws
Motherboard: Gigabyte 970a-ud3p
PSU: EVGA 500w

Is there anyway to stop the CPU bottle necking, other than upgrading as I have no money?

I was thinking of overclocking the CPU but I'm not sure if that would fix my problem, or if my PSU has enough power to overclock it.

Any suggestions would be greatly appreciated, thank you.

Don't have experience myself with overclocking, but it looks like you should have little to no trouble overclocking with that motherboard. You'll need to get an aftermarket cooler, but even decent air coolers will maybe only run you $50-60USD.

As an alternative, you have the option of moving up to an octa-core chip, including the faster FX-8370. Plus, the prior link seems to show that you can still OC the octa-cores as well. As long as it's not one of the "e" chips, you should be able to pick one up for anywhere from $100 USD (FX-8300) to ~$180 (FX-8370).

Actually that's CPU that's bottlenecking GPU but that word is a bit of misnomer because it's your CPU that's not up to the task.
Overclocking doesn't require much more power but may include some other changes, like better CPU cooler for instance and better overall cooling. MB may also be a factor.

Im actaully familiar with the FX-6300 and it usually overclocks like a champ. When I ran my FX 6300 @4.2ghz with my gtx 970 there was hardly any bottlenecking. In my opinion its deff worth trying to squeeze a little extra out of it.

Also I wouldnt upgrade to another FX unless your getting a really good deal.

I have a Hyper 212 EVO, the case was pretty cheap so the cooling might not be too great.

Would my 500w psu be safe to overclock the Fx6300? I have no experience overclocking.

Another option to improve gameplay is frame capping. Let's say your fps is swinging between 50-90, capping at 60 would give a smoother experience if only getting variances of 50-60. Large fps variances are really detrimental to gameplay. Capping your fps will reduce CPU load. Also capping at the same rate as your monitor is a great way to reduce screen tearing without introducing lag.

I've tried using vsync but the problem still occurs. I'm not sure if enabling vsync would be the same as capping my fps, but thank you for your suggestion.

Also, if you're worried about cooling, check your case manual & make sure you've installed all of the case fans you can. I have mine maxed out (3 intake/2 exhaust, as per the manual's diagram), even though I don't OC, because I've had hard drives go bad from heat issues in the past.

*Update*

I've switched my GPU back from the GTX 1060 to a Radeon 7800 and I still have really high CPU usage. Any suggestions as it seems to not be bottleneck?

Before I had the 1060 I was using the exact same as I am now and it was perfectly fine.

The reason I switched to the 1060 was because I reinstalled windows 7 without wiping my hard drive, and my computer could no longer recognize my Radeon 7800 gpu, so I thought it was a gpu problem, but i've put my 7800 back in today with no problems.

Thanks for any help.

CPU load is directly related to fps, at 60 fps the CPU load will be very similar for both gpu's. However your old gpu will require you to run your games at lower graphics settings. If a CPU cannot hold a certain fps changing gpu wont help, you can turn off settings in games that use the CPU but often there are few of these as most settings impact the gpu. Also depends on the specific game.
