I am still experiencing hiccups, which makes it unplayable. Though the hiccups is not all the time, but they are very destructive when you do some critical maneouvers, i.e. landing. I had a hiccup of 2 seconds right after touch down. Grrrr! Is this caused by low VRAM or something else? As I am watching I have about 300mb VRAM, which may be a little low buffer, what buffer do you recommend to have? The overall FPS is nice, around 30 FPS.   Edit: Running RWC and SMP 3.1.1 with a Nvi
