Temperature Throttle at 80ºC prevents me from getting a good framerate on PUBG

Hello fellas.

I'm here with a quite recent concern. I bought PUBG on Christmas, and I have been delighted to play the game. Even though I'm playing with 20 fps. After doing some benchmarks and research (a lot actually), I finally realized what my main problem was. The thing is: whenever I launch pubg, i get a reasonable framerate (45 fps in lobby, 30 in pre-game, before the game, not bad for my gpu), but whenever i get into the real game, my framerate drops quite significantly to 15 fps (increasing to 20 moments later). This is surely related to a temperature throttle, at 80º Celsius, and I'm sure of it because when I end the first game, and I rejoin the lobby, my framerate is 20 fps, just like in game. It seems that whenever my pc cant go above the 80º mark and needs to, it enters an idle mode for the rest of the game.
My main questions are: Can I stop that "idle mode"? Can I change my max temperature (i've tried nvidia inspector, it locks at 80 and i cant change it, it always resets)?

Thank you for your attention.

 

Have you done anything to prove that the framerate is dropping as soon as the system hits 80C? Which component is throttling? It should be easy to look at the CPU or GPU clocks to determine if something is actually throttling at that temperature.

 

I've used one program that I don't remember the name of but it analyzed that the throttling cause was "thermal", as it stopped at 80º. I didn't specified it but the throttle is due to the graphics card, not the cpu.

 

laptop model?

 

ASUS K550J

 

Maybe disabling BD prochot with throttlestop might help.

 

Didn't work :\ thanks anyways

 

Thermal isn't BD Prochot. Your laptop just has a cancer temp limit because these processors are not designed to throttle at 80C. These intel processors have built in throttle flags between 95C-103C, depending on model.

Unfortunately, throttlestop can't prevent thermal flags. You may try to see if you can acquire an unlocked or extended Bios setup, that will allow you access to the Bios temperature limits so you can increase them. another thing you can do is research "repasting" your CPU and GPU heatsinks, with removing the default crappy thermal paste and putting something good on. The Kryonaut hype has died down (too much dryout reports from Kryonaut handling direct die and very hot temps and degrading), so Noctua NT-H1 and Phobya Nanogrease Extreme are all recommended as thick, long lasting thermal pastes. Some people recommend IC Diamond but there have been bad batches in the past and this also been known to scratch dies and surfaces (the scratches don't do damage with this compound but it can prevent other compounds from being fully effective, especially Liquid Metal paste).

If you can youtube your laptop model, someone may already have a "disassemble" and "repasting" guide for it, which you can just follow and then buy Phobya Nanogrease or Noctua NT-H1 and repaste yourself. Combined with high fan speeds, you should keep the temps much lower.

 

Yea re-paste the cpu and gpu, it did wonders for my m17x r3, it made a 10 degree difference.

 

I would check you have the latest bios and drivers usual stuff, sometimes that can help. Then i would look at undervolting as well as that might shave a few degrees c off. It worked well for my CPU. Lastly is repaste check the heat sinks is positioned perfectly, free from dust.

This is one of the best suggestions I can think of... and while you're inside the laptop, also clean out the vents and fans from dust manually.

Additionally, you could try undervolting both the CPU and GPU... that in itself should help drop temperatures by quite a bit as well.. between 5 to 10 degrees C (depending on how low you can go with the voltage).

 

the 800M series were never great to begin with.

 

They were pretty good for their time (4 years ago)

 

Not 880M. A fiasco card.

 

"Temp throttle at 80c"
*waited for ASUS*
"What's your model?"
"ASUS <model>"

See, I waited for it. I found it. And people wonder why I don't let others buy ASUS if I can help it.

As for you OP, you have some avenues of fixing ahead of you. First, know that the 850M was not even a gaming card last generation (GM107, aka Maxwell powerful office class card). PLEBG is not going to do well on it. Now, what you can do is -

- Repaste it properly, make sure temps are as low as you can get them. Make sure your fans are clean too.
- Lock PLEBG's framerate somehow to both an acceptable framerate and one that doesn't overtax your GPU much, so that it doesn't heat up as much. RTSS is the best tool for this.
- Lower the demanding graphics if you haven't already.

You won't be able to surpass the 80c throttle, and you should actually be slightly glad since most ASUS notebooks had a 75c throttle with the 860M, so your 850M has a whole 5°C allowance that others normally don't. But it's not going to be fixable. And sadly, that's what you get for choosing ASUS.
