(Sry for bad english, I hope you understand)
I have a Asus ROG G20 (GTX 950, Core i5 6400, 8GB DDR4 ram) and a 1920x1080 screen.

I play Minecraft without mods. I have optifine, because I want AA and AF (Antialiasing and Anistrophic filtering {I can't even spell it :D} are both set to 16x). When my viewrange is set to ~22, fps is only about 40-55! Increasing viewrange causes the fps to drop and if I decrease viewrange, fps increases.

BUT, when viewrange is about 22, (according to MSI afterburner) the gpu usage is only 40-60% (Even the small-ish amount of vram {2GB} isn't a problem, because MC only uses ~1GB).

All cpu cores are only at 40-70% usage.
The 1GB of RAM allocated for Minecraft is always enough, unless I set view range to 30-32.
I haven't noticed any overheating problems. While playing Minecraft, CPU is usually about 55, sometimes even 70 Celsius (bit warm, but should not be a problem?) and GPU 60 Celsius.

I have 64-bit windows. I previously had 32-bit Java, but I uninstalled it and installed 64-bit Java. That didn't solve the problem.

I have the same problems even without Optifine. Optifine's AA and AF don't seem to affect fps very much.

So, is there any way I could get (A) Higher fps or (B) higher viewrange without fps loss? :(

Do you updated your VGA drivers?

Do you updated your VGA drivers?

But I use Display Port. So no need to update those drivers(?). Or did I just not understand that?

It means your video card driver

Yes, I have updated them.

This problem has something to do with the view range (because the view range DOES affect the fps). But why the heck are CPU and GPU usage always less than 80%??
