I'm trying to decide if I should buy the full version of Minecraft. It looks like it is well worth the $27; however, I'm afraid of game-breaking lag.
I tried the free browser version earlier today. It usually ran at 40-50 FPS. While not great, it was tolerable. Problems arose when I tried to rotate the screen using the mouse. It took the screen several seconds to respond at all, dropping the FPS down to less than 10 (the lowest I ever saw it go was 2).
Has anyone else had this problem? If so, was it also present in the full version, or did you manage to fix it somehow? Would the OptiFine mod help at all? I read in a few places that this might be graphics card issue (which is supported by the fact that I sometimes experience mouse lag right after my laptop boots up). I have an Intel(R) HD Graphics 3000.
(Also, sorry if this isn't quite the right place for this! I just thought the people here would be more likely to know what's going on, as well as how to fix it.)
Edit: What I've tried so far:
1) set render distance to short
2) updated my mouse driver
3) updated my graphics card driver (well, tried to - it said I already had the most up-to-date version)
4) downloaded Java version 6 update 29 (had Java 7)
5) removed Java 7
