Hi all,
Not at all sure this is the right place to post, so if possible please move the thread to a more suitable place. But I'd like to share as this really improved my fps (frames per second), and hopefully someone else can benefit as well!
I've had major fps issues in MWO despite decent hardware. I've been running an i5-2500k (stock 3.3 GHz, overclocked to 4.2 GHz) cpu but was getting poor performance, around 50-60 fps with everything on low, lots of stuttering, and slideshow-like performance in big fights.
Then I stumbled upon a setting in BIOS (motherboard is a Gigabyte P67A-D3-B3) called HPET (High Precision Event Timer). Out of curiosity I googled HPET, and it turns out that tweaking this function can have a major impact on performance of cpu-intensive games like MWO. HPET seems to be disabled by default in Windows 10, but there is a way of manually enabling it. Google it, as I'm not sure I am allowed to post such information in these threads. Basically it's just a command to write in the command prompt in admin mode.
I had had it enabled in BIOS, but decided to also enable it in Win10. Lo and behold, my fps basically doubled, with massive performance improvement in big fights and no more microstuttering. I used a program called "WinTimerTester 1.1" (again, google it) to check the so called "query performance frequency", and it now had the value that is supposed to be the high performance value (again, google it and you'll find out these values). When I tested this value before enabling in Win10 (just enabled in BIOS), I had a very poor value. (EDIT: In Wintersdark's post below there's a great tool for checking if you have it enabled or not.)
So, if you own a cpu similar to mine, if you experience poor performance, try tweaking the setting in BIOS and/or Windows to see if you can get better performance. I'll be happy to help out further in PM or in-game (in-game name octopec) !
