The maximum FPS you can have in MP is 100. You have to have 100 HZ or 200 HZ, else you won’t get 100 FPS. If you have 72 that means your refreshrate is 144 HZ. Just set it to 100 HZ and you have 100 FPS.
240 HZ = 60 FPS
200 HZ = 100 FPS
165 HZ = 82,5 FPS
144 HZ = 72 FPS
120 HZ = 60 FPS
100 HZ = 100 FPS
The rest i don’t know, but i think even 75 and 85 FPS get cut in half. So it would be better to just play with 60 HZ instead of 75 or 85.
