In some games it gets too hot (98c) and thermal throttled which causes severe stutters, hence I disable turbo for FH4 and FS2020. Testing ori right now temp stays in the high 70s / low 80s with turbo enabled, so not as taxing. However now I'm paying closer attention to it, it's not smooth while running either, lot of very noticeable judder, even when jumping (flying through the air) so scroll speed should be constant. It's very distracting.

My CPU does go up to 3.8 ghz while Ori runs. I see no other settings, just resolution, set to 1080p, full screen, motion blur off, VSync on. Without Vsync the judders are less, but still no constant scroll speed. More playable anyway, but I need to start over I see. No clue what I'm doing anymore, running back and forth in the same area.

No clue how to change the other settings (hyperthreading, affinity)

You can set the affinity in task manager, you just assign your game to set CPU cores. I.E. CPU Core 0, 2, 4, 6.

You *should* be able to disable Hyper-Threading in the bios, but only if your manufacturer allows it... If you can't, just keep the game off the Hyper-threaded cores in Task Manager so you aren't running the game on only two CPU cores but 4 threads.

Turbo is meant to  get your CPU hot, but after a period of time it should "settle" at a set clockrate for any given task.

It doesn't settle with FS2020, but that's not well optimized.

Here's the difference between boost and no boost on my laptop with FS2020

FS2020 hammers one core, making it boost up to 4 ghz all the time, causing thermal throttling, the large dips in GPU usage which get more frequent as everything gets hotter and hotter. Without boost fps is a bit lower, but more stable and temps stay in the low 70s. With boost my left USB port starts getting iffy after a while, I assume from the excessive heat. No issues without boost.

This was before I upgraded to 32GB ram. I cleaned the vents out as well while upgrading but it was pretty clean. It didn't make any difference for temps anyway. I have it sitting on a metal table, with a couple small woodblocks at the back end to leave a bigger air space underneath to draw in air, and of course clear space at the back to blast it away. FS2020 doesn't model the plane engine overheating, but I still need to keep my laptop temp in check :)



I tried Ori again. affinity to even processors only (0,2,4 etc) and confirmed it's only using those. Boost enabled, v-sync disabled, no heat issues (stays below 70c) yet still stutters. It's the game logic or something as it's not temporary dips in fps, the actual running speed is affected, scroll speed is not constant. Which is very annoying for a sidescroller. I guess I can play it on XBox one day, Blind forest bad port.
