Can you post a screenshot? I know about the gaps at special "tiles" like the roads. I also know why this happens but didn't find a solution yet. But thats the only place where the gaps should appear.

Btw.the other video card which has problem with transparency in Tanx is a ATI Radeon IGP 345M. I don't know if it is a driver issue or related to Asphyre. I will ask Lifepower about that.

Maybe it helps if I use another texture format.
