Hey, I know! When anyone suggests donating money, how about we offer up enough to pay Loftar 3-4 months salary while he optimizes the code forHnH. I bet that'll shut people up. If I do my math right, a professional game dev makes on average of $60-70k USD a year, so that should be around $15-20k or about 100-130k in Swedish kronor. (Based on last annual survey conducted by gamasutra.com for game studio employees.)
OP: If you want a serious answer, then you should ask a serious question and provide serious examples. We can't really do much to help you if you don't tell us what the problem is. "I'm lagging" is like telling your car mechanic "it makes noises". Unlike how a auto mechanic is going to give you funny looks and then hand you a $3,000 bill while trying not to laugh at your idiocy, we're just going to look at you and laugh because you don't even know enough to help yourself (and we can't collect a $3,000 bill for fixing a noise).
