Thank you for the help, I will try that. As for getting optifine to work, I am not the only one who has had problems with optifine, and I have tried hard to get it to work doing a lot of googling for solutions. The stuff I did find never had solutions
I always use the lowest settings in optifine putting everything to fastest except for animations. As for the flickering, that is a problem with not using the correct version of optifine for my system, tekkit and technic both use OptiFine HD A7 Smooth + AA which is no good because I get flickering on all versions of optifine except standard. Even the creator suggests that anyone getting flickering use the standard version. But even if I use the standard version I still get a drop in FPS.
Now I'm sure I'll get trolls who say I have a sucky computer like last time but the fact is this system was able to run technic and yogbox just fine before the technic launcher made it so installing optifine wasn't an option and my system has had an upgraded graphics card since then.
Nvidia GeForce 9800 GT
AMD Athlon 64 X2 Dual Core
2.19Ghz 2 GB RAM
Running Windows XP SP3
I am able to run Skyrim and Guild Wars 2(during beta 1 and 2) without lag, while I realize minecraft can be resource intensive I don't see a reason for the FPS drop I am getting.
