@Finalflash50 Nope. @Quackagate I think it works like this: If you have a fast computer, use sse-3 and that will be the fastest for you. If you have an alright computer, use sse-2 and that will be fastest for you. If you have a slow computer, use sse and that will be fastest for you.
I noticed, when using a 7 year old computer (which still seems to be better than my current one) the sse3 wouldn't run, it said the processor was unsupported. so i tried a lowwer sse and it worked. So it may be compatability.
