FC 25 STUTTERS FIXED!!!! Go on your bios motherboard and check cpu temperature.If its above 60-70 then remove your cooler fan and cpu and reinstall them.Make a research on youtube if you dont know how you can do it.If it's still stuttering its probably because you have an older version of your processor driver.Go install driver easy and check updates.If its still stuttering you can check some windows tweaking(Check Khorvie Tech's one).You can aslo overclock(safely) your cpu after reinstalling the cpu from your motherboard by just going on motherboard settings and check advanced tab where it says cpu or processor(it's different on all of us, so go and make a research about overclocking cpu safely).
!!!!DISCLAIMER!!!!!! If youre not feeling safe doing that, just dont do it, but surely its 100% safely.
