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
 
Could be Windows + 100% writing to disk, as well. You can verify by using an on-screen display which shows writes to drive percentage so you can see if it coincides with those occasions.
 
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.
 
Thermal throttling from CPU or GPU is possible.
Run HWMonitor and check your CPU clocks and your GPU clocks while in game and see if they ramp up as they should.

Monitor temperatures as well. How hot are things getting? 10 series Nvidia cards will try to stay at 70 degrees celsius at stock. If the fan has failed on the card it will throttle severely trying to maintain 70.

Also could perhaps be a power issue.
 
I had a similar issue after an Nvidia driver update recently (the one before the current one) it drove me crazy. So i done a BIOS update and it cured it.... no idea why or what caused it but it did. worth a shot if your not on the latest bios. But for me it was the nvidia drivers that caused it.
 
You haven't ran Driver verifer and not reset/stopped it have you?

Only reason I ask is I was trying to find the source of my system crash so was using the driver verifier...then I forgot I had it running ans started to try play cs and also BF1 with terrible FPS.

Stopped the driver verifier running and all went back to normal.
 
Have you got access to another psu that would power the system?

While the other suggestions are likely the cause, the VS range of Corsair is the lowest quality and weakest in its whole line up so could be failing slowly? That or the motherboard is slowly failing.
 
Download HWmonitor from the CPUID website. It will give you all the info you need to (probably) diagnose this problem.

Check CPU temperatures, check CPU fan speed, make sure the CPU is ramping up to its full speed when doing intensive work such as gaming

Check GPU temperatures and fan speed, check GPU utilization, and GPU clocks. Is the GPU getting up to or near its fully rated speed? What is the temperature? What is the fan speed? Check all fans to confirm that they are spinning.

Another possibility if this is a thermal problem is that your CPU cooler has come loose.

Report back when you have more info :)

BTW you are frequently blowing all the dust out of your computer and power supply especially heatsinks/rads? Yes?

(Btw never put anything IN your power supply but aiming a can of compressed air at the power supply without jamming the nozzle in is fine.
 
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.

Is the power supply at the top of the case or bottom with fan facing down?

It's at the bottom of the case. I'm not sure how I would know the fan was facing down tbh? You I can see the fan on the very top of the psu when I open up the case?

I'd open the case, and leave it open while you stress the system, check that the PSU fan is running.
