I'm sorry for making so many discussions, but G64 causes FPS drops compared to any of my other addons, even when Mario isn't even on the map. And for the cache overflow, some maps (such as gm_bigcity) do not work properly and kick me out a few seconds after it loads, saying something about a cache overflow.

Update (February 2025):

I recently tried the addon again, and the method I used to fix the cache overflow is use the console command "g64_disable_cache". Recently the FPS drops have mostly gotten lighter, however, playing on maps with loading zones (Such as the Half-Life 2 maps) eventually kick me out of the map after like 4-5 loading zones.
