My computer just got back from being repaired and I had to re-install the amd catalyst control center. And I have been setting java.exe to high performance in "configure switchable graphics" so when I play minecraft I get waaay better performance. But now I cant find java.exe to set it to high performance. I can find minecraft .exe but it doesnt work. I already tried re-installing java but I still cant find it. I only get around 20-25 fps on minecraft playing multiplayer on average with lowest settings. I would really appreciate some help.
