SC4 doesn't seem to like my PC either. Since a couple of days, SC4 is going really slow on my PC for no apparent reasons. I don't have a lot of plugins to keep everything running smoothly, but still it runs very, very slow indeed, even with all grapic options set to low. Some specs: AMD Phenom triple core 1.9 GHz 4 Gb RAM NVIDIA GeForce 9500 GS (1024 Mb) Vista Sp1 64 bit The really strange thing is, that on my old laptop (2GHz Athlon, 1Gb RAM, 128 Mb video, XP sp2) the game never displayed such troubles while having the same plugins... If anybody knows a solution to this... Thanks.
