What changed?
Updates: • University is so tough :< my mind feels so confused as I keep studying for exams. • There wasn’t much time to work on the modpack, and now there’s even less. During my spare time, I experimented with creating this Vulkan build. • In terms of performance, this build is really good. The FPS is very high (probably because there are fewer mods). The downside is that only mods not using OpenGL can be added for optimization :/ but overall, performance is excellent and the number of mods is quite small. In general, it’s very suitable for PCs with low-spec AMD GPUs that still want high FPS. • For anyone who wants to make their own Vulkan build: add -Dorg.lwjgl.system.stackSize=256 to the JVM Args as shown in the picture, and it will run instead of crashing. \ Add -Dorg.lwjgl.system.stackSize=256 to the JVM Args
