GPU won't fully utilize.

[RustyRust]

My GPU usage is anywhere from 10% and 40% when I play minecraft w/ shaders while GTA V, Far Cry 3, Black ops 3 and tons of other games fully use the GPU to 99%...

I can't figure this out because just last week minecraft was using my gpu to 99% so I have no clue here... I don't think it is a CPU problem because it's only at 40-50% usage when playing... Honestly any help on this would be great because I've tried everything including reinstalling minecraft and java.

Specs:
i3 3250
GTX 750 Ti
8GB RAM

Do you experience problems while playing minecraft if the gpu is not using 100% of its resources?

Minecraft isn't very GPU intensive. Do you have Vsync On? If so turn it off.

Hello... There are typically three programed speeds in the GPU firmware/BIO's... it will "Switch Gears" as the APPs calls for it to do. This is all for Energy savings, changing your Gaming/video settings, Can change the Speed the GPU will run at.

I didn't mean to pick answer... But yes, when I am playing with shaders my frames are about 20-30.

Minecraft have a very large field of view.

Gpu is low on memory to load all textures with shadders

Well last week it was running fine... 60-80 fps then.

🙁

I'm using SEUS shaders.

Try again on a new world.

Check if performance are similar.

I've tried on new worlds, old worlds, servers... Same results...

Try comparing performance without using shadders

Without shaders I got 400-500 fps with 40-50% utilization.
I turned it back on and the utilization dropped back down to 10-30%

Its a memory issue.

A very simplified explanation,
when the gpu lacks memory, it uses pagefile to load game resources (shadders), but this is slower than using gpu memory.. And so on.

Basically, the gpu can't handle your minecraft mod

Oh... Ok, Well I don't know why it was perfectly fine last week... Thanks for your help.

EDIT: I checked the memory usage when playing and the highest it got to was 33%... I don't know, I might just reinstall windows.
