silentcobra3 said:Take Fortnite, for example (any settings, even if everything is set to low)
It keeps dropping from a smooth 60fps down to 15-20fps, and then it just hangs at around 15fps for maybe 10 seconds before bouncing back up to 60fps.
Getting Over It (everything on low)
Same exact situation—drops from 60fps down to 15-20fps and then fixes itself after a few seconds (maybe 5-10 seconds).
GTA V
It usually runs around 50-60 fps, but then it drops to 5-10fps and then recovers.
I honestly don't know why these drops are happening, but that part where it gets stuck at a lower fps for 5-10 seconds might be due to Vsync. That's just how Vsync works, I guess—if it can't load all the frames, it drops to half sync, which is usually 30 if you have a 60Hz monitor, but if the drop goes below 30, it might stick to an even lower value. I think it has to be a divisor of 60 (like 30, 20, 15, 10, 5), though I'm not entirely sure. I've never quite wrapped my head around exactly how Vsync operates.
You could try turning Vsync off and see if anything changes, though you'll probably deal with screen tearing. Or better yet, turn Vsync off and enable Enhanced sync under the Wait for vertical refresh setting within the Nvidia settings profile for that specific game. Sometimes that actually yields better results.
Though, none of this really explains why the actual drops are occurring in the first place.
I doubt it's the RAM because Windows usually throws that "Windows is low on memory..." warning if that's the case.
Maybe it's the VRAM, but that shouldn't really happen on low settings since your whole setup seems beefy enough to handle high settings easily.
Is it possible some other background program is occasionally hogging the CPU, leaving nothing left for the game? You could try playing around with the CPU priorities for individual programs.
We should probably check if your voltages are stable. You mentioned a 500W power supply, but you didn't say which one.
The best bet would be to grab HWInfo, reset the sensors, and run the game. Once you hit those drops, close it out and look at the min and max columns for everything to see what kind of extremes you're hitting. Specifically, keep an eye on the voltages—see if any of them dip way below the average. That could point toward a power supply issue, or maybe an overclock that's too aggressive or unstable.
I have the same graphics card and a motherboard with a similar phase design (but it's Intel) and I highly doubt that's the culprit. For me, GTA V runs without any issues at around 60 fps on most High settings. That phase design might be an issue if you're doing heavy overclocking, but at stock clocks, it should work fine with any processor for that socket. I mean, they test this stuff, right? God knows.
