Vehicle Simulator looks really promising. There are a few issues but it is impressive if it's really done by only one guy.
I hope he will get a lot supporters and i guess 3rd party developers would be able to influence the development of Vehicle Simulator.
BTW, Do you think it would be possible to completely replace all shaders of FSX with SM3.0?
FSX doesn't run really well on cards which are only supporting SM2.0 and i guess there is a potential for optimizations.
EDIT: Whats the purpose of the "Water203D..." shader files?
Great shots slaWter!
I like the water.
