Very recently i brought over an old single player world save to my new computer because my old one couldn't handle it anymore and it was fine fps wise for a while but when i went out side my spawn area a bit the fps just tanked so i waited a bit assuming it would go back up because it was just loading in too many chunks, but it never did so i just deleted my save and decided to go on multiplayer and in multiplayer my fps was bad too and normally i got 60 fps on both single player and multiplayer so i decided to completely delete Minecraft and reinstall it after that whenever i opened the launcher it came up with the error unable to start Minecraft runtime environment after many failed reinstalls i found another way to launch Minecraft and just put a icon over it i found off the Internet to make it look like the normal launcher so since thats somewhat fixed i played multiplayer which was fine in fps, but every time i play single player it kills the fps and i have to redo the whole process and i just want to play single player again. Plz help i love Minecraft and i would hate to never be able to play it again.
