This is just to complete some thoughts I had about the subject of this thread over the last few months. I've gone back to work full time so I won't be putting any more effort into it. It's probably not very useful but since it kind of works I'll post it here. I was looking for an alternative to alpha fading impostors (billboards). As you will see, by the brevity of the code, the shader does most of the work. Hope you like it.

For you dial-uppers - sorry, the project is heavy on the media and weighs in at about 2 megs.

Just curious. I only have access to ATI video cards and I know there can be card specific differences. Is this crashing on other cards? Is it running for anybody? You obviously need shader capability to test it.

LOL! Thanks roka - I guess I'll have to target a minimum spec of sm4 and 250 megs of vram since we seem to be the only ones who can run it.

I've just tried it on my notebook; Acer Aspire One with Intel Graphics Media Accelerator 950 (inbuilt graphics).

Runs a treat at ~99fps.

I get 65 on a ATI Radeon X300 256mb VRam. Not sure if the 65 is a vsync limit or what will check that out now.

Edit

When I changed the res to 800x600, it jumped to ~180 and at 640X480, it went to ~220, so it was not the vid card. Heh, I need to update my comp soon.

I regret getting a notebook with an integrated GPU.

Well, it's tolerable -- about 70 FPS. Though, I'm not quite sure of what exactly is going on in this test. I don't see any increased detail when getting closer to the tanks.

Unless that wasn't the intention, then just disregard this.

Currently working on - Enemy AI using Dark A.I. I probably should've looked at the reviews in the Dark Physics and Dark A.I. forum first.

It runs on my ancient machine at a steady smooth 60 fps.

PC specs:

Year Purchased - 2001
Pentium III, 930MHz
256MB RAM
GeForce FX 5200, 128MB (max shader model SM2)

[Edit: the GFX card is NOT the original - I upgraded that 3 or 4 years ago, the rest is the original machine]

Thanks guys. I would have thought that the 2048x2048 image would bomb on some of those integrated chips but am glad to see it doesn't. I guess twenty first century technology has overcome my crappy coding skills once again.
