As always, the anal retentive SW has told us where to post. Now as soon as he starts paying for my Aces High account, I will listen too him.
As far as a frame hit, there would really be none. What zigrat is talking about would be a transparent texture, and a very small one at that. For axample, the smoke that comes out of planes when you shoot then, are made up of hundreds of textures. What zig is talking about would be just one texture per plane, so even if you had 20 planes on the screen it would still be just 20 textures as oppsed to the hundreds that spew from a plane every time you shoot it. I think its a great idea.
