Description

I'm using linux, I tried both fedora and cachyos. I tried different laptops.
The game literally stops for two-three second in every one or two minutes. I have seen some java arguments in forums they are saying the garbage collection thing is problem but the commands did not fixed. I tried photon, bsl, bliss, compementary shaders. All results are same. I thought some performance modes might be problem I disabled them but still same.
But there is a thing that I notice, when I set the max memory to 16GB, the drop took longer. Maybe they were right about the garbage collection.
Also I'm using prism launcher.
The laptop I'm currently usin specs:
RTX4050 70W(laptop), i5 13500h, 32gb ddr4.

Research direction

Start by reproducing the periodic pauses in Voxy with the listed shader packs through Prism Launcher on Linux, then inspect the available logs or profiling output to distinguish garbage collection from shader or rendering work. Done means the pause cause is isolated and the fix is verified across the reported setup or the issue is narrowed with actionable evidence.
