Hello!

My problem is that, after i play a game for a while (Far Cry Primal, Rust or whatever) my fps drops heavily. If I restart my pc the fps is normal again but only for like 15min when it gets bad again and I experience like micro-lags while my fps is still over 60. I have checked my temps its all good (CPU never over 60, GPU never over 70). I have ran windows def., nod32, malware and its all clear. Also cleaned the pc but none of these solved the problem. My memory is also good there are a lot of room for applications. I have no idea what to do, dont really want to reinstall my system :/. I hope you guys have some solutions for this problem.

Now im sure, after my GPU gets stuck on 1228MHz for some reason i get low fps and micro-lags in games. It gets stuck for no reason im doing literally nothing on my pc. When i restart my pc it is normal, but after a while (15m) it gets stuck again and i cant play.

Thanks in advance!

System:
i7-4790k 4,4GHz (overclocked a bit)
ASUS MAXIMUS VIII HERO
16GB 2400MHz HyperX Predator
Gigabyte G1 Gaming gtx 980 (no overclock)
Cooler Master V850

if you have a spare hard drive (40gb would be enough) remove your main drive, and basically fresh-install windows on the extra drive, and then just the basics like video drivers and one or 2 games, then test again, i had a friend with a micro-lag problem that we tried to fix for the better part of a year, and when he did a 'fresh' windows on another drive, it magically dissappeared

Just noticed that my CPU clock is bouncing randomly from 800MHz to 4400Mhz.
Sometimes my GPU clock stucks on 1400Mhz but i dont do anything, not even overclocking just using a browser. And as i notice it gets bad when it gets stuck.

just something to see if the 'auto-turboboost' is part of the problem:
Go to Control Panel > Power options > choose High Performance

this will make the cpu stay at 100% clock, where windows normally downclocks it when things aren't using it

let us know if this has ANY change

Edit: also i've seen a windows 10 issue where if you don't have an Anti-virus installed, Windows Defender goes nuts and does a full scan whenever it wants, whether you're using the computer or not, it doesn't seem to care, so maybe install a free antivirus and see what happens

ok things i've seen cause FPS drop in my own expierence:
- F.Lux (only when it's changing the color, which is 30 or 60 seconds)
- Samsung Magician (not sure why)
- Discord (seems to have some sort of issue after it's been running a long time, but hasn't happened recently, so might've been fixed)
- motherboard overheating, so it throttles back the CPU to cool itself down (this was an AMD 8350 on a cheap board, so the processor never overheated, but the chipset did)
- obviously overheating video card
- full Disk usage (many reasons)
- windows update (when checking for updates, it uses a crap-ton of resources and doesn't care)
- Malfunctioning video card (i had one that was dying, and it would be horrible FPS all of a sudden mixed with bluescreens and "display drive has crashed and has been recovered" messages from windows)
- bad RAM (have you run several passes of MEMTEST86+?)

maybe some of these will give you an idea??

Edit: you mentioned that the GPU gets stuck at a specific frequency, have you tried clean installing drivers again? or even tried a different video card? (maybe onboard just to see if it still happens)
Getting stuck like that might mean the card is defective, or the program your using to monitor the voltage etc. might be causing issues

Ive tried everything u said but none of them actually helped, i did removed and reinstalled my drivers using DDU.
I didnt try to replace the card bc i cant do that yet :/

How much ram do you have? Is it a 2x8 or 1x16? This can have a pretty noticeable effect on performance if you're running on single channel ram. If you're on dual channel it's probably something else going on.

If you are on single, grab yourself another stick of the same model, or get a 2x8 or something.
