GPU temperature too high when playing the game

[Venom Snail]

I have a Geforce 970, and I noticed I have a 70c temperature when playing this game. V-sync is off, and games like Witcher 3 or GTAV are not even close to the temperature I get when playing Hollow Knight. Framerate is also limited.

Have you tried enabling vsync? The frame rate cap option doesn't do anything.

As said, the in-game frame cap is broken. Use a third party application like Rivatuner Statistics Server to limit your frame rate to something sane like 2x your monitor refresh rate. If you have a high refresh rate you could also turn on vsync, but for lower refresh rates this will cause noticeable input lag.

V-sync was disabled, before I created this thread I made a quick search and people suggested to turn v-sync off. So is there no way to make this work without another software like Rivatuner or Nvidia Inspector? No possibility devs will fix the in-game frame limiter?

Gotta be honest this is the first I've ever heard about any of this. I have zero issues when running the game at all no lag or temp problems. What is your over all setup?

So... did you try enabling Vsync? Apparently some people do have input lag when using Vsync but I've never had it on my system and I have a 60Hz monitor

Actually if you make a quick search on Google there are other people with the same problem. Also I tried to enable v-sync and nothing changes.

Cap your FPS to 60 or 144 depending on what monitor you are using. I am using Riva Tuner for fps cap for all my games.

Managed to solve the issue with RivaTuner, but devs should really fix the frame limiter, because you can seriously send to hell your GPU with uncapped framerate like the one I was having. Now I have a 38c temperature when playing the game against the 70c I had yesterday.

My Radeon 570 fans spin to full when playing this game, and I sometimes experience lag, free sync was off (limiter on, although I know this is broken now), I also use the Radeon Chill FPS limiter, the fans still spin to full. Will try Vsync, so potentially Radeon Chill is also broken for this game. Point of reference is when I play Dota (maybe 90% max settings), and frame capped to 60fps, the fans only spin up this high on rare occasion.

With vsync on GPU fans no longer spin at full, but there is some stutter as expected.

Edit: The Radeon Chill feature is not broken maybe, if I set in fps cap to ON, Radeon Chill seem to do nothing, but setting the in game fps cap to OFF, Radeon Chill does appear to take effect. And frame rates are smoother.

Edit 2: Fan still pins up high when playing the game, will try the solution posted below. Possibly because AMD will defer to game settings, and game is explicitly controlling the FPS either with limiter or not. I'm just guessing.

Be careful with bumping threads from far back; the information in old threads is likely to be outdated. That's also the case here. The frame rate cap is not broken! It just limits the frame rate to the setting in the game's config file, which could be set to 400 or -1.

To get it to work as intended, modify the defaults config file (which can usually be found in C:\Program Files (x86)\Steam\steamapps\common\Hollow Knight\hollow_knight_Data\Config.ini ) to a sane setting like 60 or 120 FPS and turn on the frame rate limiter from the in-game menu and it'll limit your frame rate. If your GPU's fans still spin up after that, it's just because the game's not very efficiently written and your GPU actually has to do work.

Note: vsync should never cause stuttering by itself. If the game stutters, check whether you have any other programs running that might periodically use resources that could cause the game to drop under 60 FPS (which, with vsync on, would immediately delay a frame by two refreshes, effectively dropping your frame rate to 30 FPS)
