Just stared having FPS issues, Have fastcraft installed and Optifine, was running 110 FPS Yesterday, Now it's giving me 40-60 frames at my base, but it feels more like 15-20 FPS. Tempted to go back to previous patch and see if that increases fps again, but first... Time to go to work
Have 5 Gb of my 8GB RAM dedicated to MC, however pressing F3 its only using about 1.2 - 1.8GB most of the time,
8320e AMD CPU 3.2 GHZ with 4GHz turbo (not sure if Minecraft uses that though)
760GTX
I'm wondering if it is a taint related issue, as Twilight forest I'm getting better FPS, (still not amazing but I never have in there).
Anyone else had this issue? Possible fixes?
