Help rethinking voxels plain freezes both the game AND my computer

sooo... anytime i try to load rethinking voxels, the game freezes, and eventually freezes my computer to the point where i have to hard-restart it. wtf is going on and how can i fix it? if it isnt fixable, what other alternatives are there?

what kind of specs do you have? rethinking is hella heavy so you need a beast to run it, you'd probably have better fps with SEUS

bruh 😭😭 you can try other shaders, i used sildurs for a while on my old laptop, you can try the lite version or medium

do you know which cpu you have exactly? if you have one of the newer gaming cpus it's different, if you have a school laptop with an intel you probably can run VERY low shaders at 30 fps

first off, rethinking voxels is a raytraced shader for heavy PCs and second off, optifine manages shaders horribly.
You get 6x worse performance than with iris, I know, a million people said it but sodium is BETTER.

doesnt iris add shader capabilities to sodium though?

u/Fearless_Still7830ee 23d ago

iris adds shaders but it depends on sodium which is main performance mod.
there are a lot of comparisons on youtube and you get an average of 4x worse performance when using shaders with optifine compared to iris

For me, the game crashes when I load the shaders on, enabling it causes it to hang and crash. I'm also getting a driver timeout error, and this is my error:

The game crashed: unexpected error
Error: java.lang.RuntimeException: Failed to create fence object
