After hours of research and testing, i came up with the folowing working code:

What might cause these graphic glitches?
|
Hi,
i've been trying to figure this out forever.
The water and the terrain cause some weird graphic glitches. They become worse the greater the camera distance is. It looks ok when you're close though.
I have tried all render states i could... |

Nice work. I've been meaning to look into virtual texturing for a while now.
Does your source include the asset generation logic?
Yes, it does, but my tools aren't as comprehensive as ID Software's yet ;)
You ca... |

Your last idea sounds very much like mega texturing - a.k.a. virtual texturing. Recently someone posted a demo implementation in the graphics forum. The developer has promised to release the source code.

I cannot wait to get home and try this.
I also can't wait for the source, I could never get the texture streaming from disk to work in my implementation, so I was "mega"texturing with 4096 x 4096 textures and paging fr... |

Thanks guys! The mip map artifacts some of you see seem to be specific to the 8000-series. I'll look into it. I assume you have the latest drivers.
The good news is that i just presented the demo and everything worked pretty well! It was damn slow... |

Forgot to mention that I was getting 600-750fps (1024x768, Max Tris 10,000, PNG Compression 9) and it looks very good.

That is extremely cool. I hadn't realized the full impact of what it's like to be able to walk up to a 3d texture and never see it pixelize. Amazing. I got a solid 200 FPS give or take 20,
Thanks, Funkymunky!... |
