hey guys.

Currently scratching my head trying to resolve an issue that has come up occasionally and now it is worse than ever.

In any game, I’m getting sudden and consistent FPS drops that are completely insane.

As stated in something like csgo I’m getting 5-10fps and stutters instead of butter smooth 200+

I’ve tried malware scanners.

Disconnecting hardware and reconnecting it.

Leaving parts of ram out.

I’ve tried switching pci-e connectors.

I have also checked temps and nothing is out of the ordinary.

It’s driving me crazy.

I have

6700k not overclocked
32gb Ram - Corsair vengeance
1080 gtx
2 SSD Sata

Can’t think of anything else. Any ideas of what could be causing it?

All drivers updated?

Try putting an FPS limit in games through MSI afterburner/RSS

Have you recently downloaded any windows updates?

Yes drivers updated.

Not tried a frame limiter

Yes but this was happening before the windows update.

It’s now at the point that I can’t actually play games at all. Where as before it was an inconsistent problem
 
I checked over the fan. Thank you for that one.

I'll check the disks.

Now here’s some peculiar.

The bios was reporting the cpu at 0.8ghz.

I reset the bios and it all seemed to be working fine until I was about 3 mins into a game and the issues came up again. It wasn’t as terrible and as long a drop but they still happened sadly.

So back to trying to figure this out. That seemed to be a breakthrough.
 
Hi thanks so much for all the replies and help.

I've covered all of them so far and I have been using HWMonitor.

Weirdly, it seems when the heat of the 1080 increases to about 80 degrees, it seems like my performance is then exactly as expected.

The only thing I can't rule out right now is the power getting to the whole system. I'm loathed to buy a new one if it isn't going to be the solution I need.

Having said that, despite the trust I have in the Corsair brand - this does appear to be a poor quality PSU. So it's knocked my confidence overall in the actual performance of it.

Could the GPU really be struggling to get power to it, hence the heat increasing on better perfomance?

Corsair do sell excellent PSUs. VS range isn't for gaming with GTX 1080 even though spec-wise it can provide enough power (600W on +12v rail/s under optimal circumstances), they are advertised as being for general purpose/everyday computing, i.e. nothing too stressful. Corsair make them because there's money to be made, i.e. plenty want cheap PSUs. They obviously cannot advertise them as "unfit for mid-range or higher gaming systems" as that's a negative not a positive, but they pretty much indicate so, and if you were asking advice from a Corsair rep on a PSU to buy for that system they wouldn't tell you to get a VS.

Having said that, yes it sounds like your 1080 may not be receiving enough power consistently so PSU is suspect. Any chance of trying to use two separate PCIe cables if you're only using one cable with two connectors, or something like that?

And for the record, which model of GTX 1080 is it and which case is the system in?

Ok I’ll try the separate connectors and see if that gives temp relief.

It’s a founders edition 1080 and the case is a non-branded 30 quid job. Fans through out and the like. It wasn’t meant to be a long term case.
 
Done another test run on pubg. It seems that frame rate directly correlates with the heat of the GPU or I could just be reading too much into it. Need to run it for longer.
 
Same problem with this PSU.

What I have noticed is a direct correlation with power usage on HWMonitor and the fps I am getting. It's sticking at 25-30 percent power and when it ramps to 100% I start to get the frames I am used to.
 
Tried the 1080 on a different computer now.

It seems to be running perfectly fine.

I've now put a 1060 into my machine and a different power supply and getting the same issues.

I find it hard to believe that this power supply (550w Superflower) can't power a 1060 or a 1080.

The power usage according to HWmonitor is 14 percent even when on intensive GPU games.

So I'm still no further to finding out what on earth is going wrong.
 
I forgot to tell you all what happened.

So the answer was in front of my face and I mentioned in this thread.

The CPU was constantly locked at 800mhz - hence the massive drops in performance.

The culprit was: Intel Thermal Monitor

Well, the actual culprit was my cooler was too tight on the CPU so it was tripping out the thermal monitor.

When this happens, it forces the cpu down to 800mhz.

I disabled it at first and then rejigged my CPU heatsink.

All fine now and in fact better than ever. Which makes a hell of a lot of sense now because I must have been having a minor performance hits thanks to the throttling.

Hope this thread helps to contribute to someone else sorting out their own PC in the future.
