I'm just going to buy it. $40usd is cheap even for a couple of FPS and it will surely milk more than that out of my core2 quad 3.0ghz. Besides, I like the idea of supporting these guys that have spent tireless hours coming up with very very specialized, complex software to help our sims improve. If a few people want a 50fps increase for the price, then they need to reassess and then come up with a grand for a whole new system. I can assure you that 98% of sim users tweak their cfg's but actually don't have a any idea about writing actual API code to do this kind of thing. The amount of research just to begin such a project then experiment/debug/release/support is huge to put it mildly. I don't mean to be offensive to that 98% of my fellow simmers, I am just stating the reality of it. Sorry, I just always like to defend developers- except those who gladly accept paypal then decide to disappear or delay once the normal questions and support start coming on in. I have some other prods from fsps and they have great support - like giving us a 60 min demo now.
