As I found out recently myself, you should almost always set the minimum amount of reserved memory for the iGPU on modern hardware. The reserved memory is just that— reserved. The kernel still dynamically allocates memory for GPU usage as needed on iGPUs.
I have 8gb and I assigned 2gb to igpu because I already have 8gb of zram, I’m not sure what difference it would make tho

Really?, so I should set vram to 256mb and everything should still work fine?
Yes, iGPU can use system RAM
