70-80 FPS to 7-8 Fps instantly

I deactived all mods. have settings set to normal. lets say on utah map I go from having 65-80 fps to an instant 7-8 fps happens every few seconds. In the tunnel I go from 140ish fps down to 9 fps every few seconds. acer nitro 5 Laptop Gtx geforce 1050 8gb i5 8th gen. any ideas?

 

Temps? Laptop plugged in? Do you have an SSD that's filled over 90%?

 

Temps usually run around 204F=96c. I think. Yes plugged in. No ssd. just hdd and it has 53% available space

 

Sooo I have a cooling pad and the wires burnt up on it awhile back. Well I found a 4.5v wall charger cut the end off and hard wired the fans to it, they are 5 volts a piece. Started the game up and watched the temps they were staying around the 80s to low 90s and it still does the lag thing. I have a few older computers I might take a couple more fans out of them and add to the cooling pad and see if that helps. But one thing I find weird is as soon as I close the game the temps Immediately drop to 60s. is that possible? To me I would think it would need to cool off but to drop 30+ degrees in seconds?

 

It's quite reasonable for the temperature to drop off very quickly. Rather than monitoring temperature you are better off checking the clock speeds and overall utilisation. CPU can be checked from task manager and something like MSI Afterburner for GPU. Open the game and monitor clock speeds and usage before and during the FPS drop, do they stay constant?

How does the machine perform in other intensive games?

 

Played GTA5 first time was at 60 fps and would drop to 30-40 fps. Second time it stayed at 51-54 fps and I could drive 100+mph while it was raining and lightning.(in game)

 

My cpu hovers around 60% during game play but as soon as the lag hits, it drops down to 15%. Now I just need to figure out how to find the gpu thing

 

Clock speed is dropping, goes from about 3.8 GHz down to .78 GHz

 

I did an under volt thing and it seems to be running a lot better.

 

oh lord yea it sounds like your thermal throttling. would be worth your time if it dosent void the warrenty to tear down the laptop and do a deep clean and repaste.

 

I'll have thermal paste on the way soon. Well I say soon but its been in the cart for most of the day as I continue shopping for a bunch little stuff thats not really needed or pc related lol.

 

Use softwares such as ThrottleStop to force your CPU clock at rated speeds.

 

Only if it's got thermal throttling, it's not worth burning up a CPU for 70-80 FPS.
My tip to you is since it's throttling so bad is to lower the max frame rate to like 50 FPS, it reduces strain on the CPU by a massive amount and you'll only notice a small difference in framerate, after 60 FPS the human eye can hardly see a difference anyways, which is why it's such a common goal to be able to run a game at. Also, put a fan next to your PC to make sure it's not just sucking in it's exhausted air through it's intakes. Hot air doesn't seem to keep things cool too well for whatever reason, hahaha. On my old case though, it had a STRIX RX570 shoved in it and it used to get grossly hot due to a lack of space and cooling fans. I swapped everything into a mid-tower and have 3, 120mm fans now and have no thermal issues now.

 

Understood. However I'm curious about the CPU "thermal throttling". On my computer when the CPU is overheating, the clock speed will gradually decrease to maintain a 95°C temp, at around 2.4~2.8GHz, throttling disappeared after i did clean the dust. I didn't notice any computer that I had used to have clock speed jumping between rated to lowest.

 

Well I replaced the paste with some new thermal paste and cleaned a lot of dust out of the fans and I used intel's program(ETU) and under volted to about -160 and the temps dropped pretty good and the game runs better. I started out at -125 then moved to -150 then to -200 it shut down, backed down to -180 it also shut down, so I tried -170 it worked for awhile but eventually it also shut down, now that I have gone down to -160 seems to be good.''for now''

 

As someone who got my pc repaired for thermal damage due to faulty fans (thanks acer) what pc do you have? how new is it? if it new get that checked, for more than half a year i thought 95°f temps were normal, i was informed that my pc was running 20°f to hot and my gaming performance suffered because of it.
