with win 98 I tried it with a fixed size of a swapfile but it was not better than before.Some say ,one should fix the size of the cache , not much better. Its a problem of win98 ( ME should be worse) and the handling of memory. Specially I had the problems with textures that used large bumpmaps.Using the same textures without loading the bumpmaps solved the problem. But i my opinion XP (or WIN2000) is the better os.
