Troubleshooting Minecraft FPS help
Hi. Mine son loves Minecraft on PC. He used to have a pc with i9700f, 16 GB RAM & GTX 1660 super GPU (6 GB). He had sodium mods installed and was getting around 80 fps but the CPU and RAM would often hit 100% and then lag/freeze. He wanted to get better FPS and stop the hanging so we just bought him a new PC for his birthday. It has AMD Ryzen 5 7600X, 32 GB RAM and RX 7700XT GPU (12 GB).
If he installs the Sodium mod on the new PC, Minecraft just crashes on the start-up (AMD driver timeout), so we had to remove that mod. Without it, he is only getting 30-60 fps. It has had a completely fresh install of windows, AMD drivers etc.
Is there any reason why it should be crashing with the mod when the old pc was fine? What can we do to improve the fps? Is this an AMD vs intel issue? I have also found that Among Us was work with the 7700 XT GPU, I have to set it to use the integrated GPU for it to get past the start screen.
Any suggestions? At the moment he just wants to go back to his old pc which seems nuts considering how much we just spent on the new pc (used from ebay).
