Hi! I've been using complementary unbound shaders - high (default) profile and i usually get 70fps stable with my gpu under 70%, also 10gb allocated to minecraft, when i start playing the game, after around 20 minutes my fps drop badly, I realized it has something to do when my RAM drops from 70% back to 30% (i guess ram just cleared itself), but that generates a lag spike (normal since it's a large modpack i guess) and then takes 5 fps until i start getting only 30 fps after 20 minutes have passed.
I already tried some stuff to fix this without success:
- Restart video drivers
- Restart chunk rendering
- fix fullscreen resolution, change to windowed, etc.
-change vsync on and off.
-close everything in my pc...
One thing i DID notice, is my gpu usage goes from 70% to 25% while around 30 fps, so it must mean something is preventing my pc from using all its resources, any solutions?
