As I mentioned above, I am running i5-7500/1060 and I can get a stable in town 75 fps at 1080p with everything set to very low or disabled and I am willing to allow my GPU to get to 70-75 degrees C. If I remove all limits I get 100fps in town at the same settings… but the GPU maxes out and stability becomes an issue with much larger spiking.
For normal play I usually run at 60 fps to keep my GPU cooler and I have zero variance in FPS in a static place like town or in a map where I have cleared the mobs… The only time this spikes is in known FPS killer moments with lots of mobs, lots of minions or lots of skills proccing… 90-95% of the time during normal play (and depending on the build) I get between 45-60fps. probably averaging at around 50-55ish.
I do not use vsync… the foreground framerate limiting option works better… Yes, vsync should have the same affect but I find that it doesnt for some unknown reason.
You should DEFINITELY be able to get similar if not better performance depending on your CPU…
