i've been working on fixing my pc's performance issues. i have a cpu that's limiting its speed. my specs are listed in my profile. i wanted to play the original game again, but it wasn't working well. the mouse would lag and drop to around 30 frames per second on low settings. i decided to test by turning off hyperthreading and saw the difference. it improved noticeably—consistent 50fps with v-sync capped at that, textures were boosted to ultra, and the mouse stopped stuttering. however, my geekbench 4 single-core score only increased by about 400 points. it ran smoothly on a windows vm with six cores and my r9 290x, using fedora linux. what changed so much when hyperthreading was disabled?
In both scenarios, six cores were assigned. It was only with hyperthreading that 12 of the 24 threads were allocated, maintaining six cores.
With hyperthreading, the threads tend to be less powerful compared to running without HT but with HT enabled. You'll see 6 logical cores, whereas without HT you'd get 6 physical cores.
I recently went through Crisis a few months back. For the highest FPS you need windowed mode; full screen settings seem to cause issues. I added a borderless windows app to improve the appearance. FPS increased from 50 to over 100 (without VSync). I’m not sure about your hyperthreading problem, but that’s what I did to play Crisis.
Hyperthreading provides only around a 30% boost in performance when disabled. It might have been that Crysis or Windows didn’t like running inside a VM (just guessing), or perhaps the graphics card wasn’t happy with it.
