Blinking texture

[mztulip]

Describe the bug
As presented in video. Similar effects appears also when entering and leaving water.
This effect mainly shows in the way to this temple. In other parts of the world I am not sure if this happens.
In this place it brought my attention.

Hi, @mztulip !

Yes, there are few of this. About 3-4 polygons in whole game. Here in landscape mesh 2 different polygons, with different materials have exact same world coordinates.
In vanilla it's not really an issue, as it renders level sequentially. OpenGothic runs stuff parallel on GPU and order of polygons been draws is subject to a chance (witch gpu core happens to be faster in a moment).
I don't really have great solution: sort polygons, serialize parts of workload or use task-shader is not really acceptable: we will lose performance for relatively minor outcome. Maybe we can do some pre-processing and filter those polygons away from meshes, on level loading (load time will take a hit)

Thanks for explanation.In this situation I think it is not resolvable without mesh editing. Therefore I think we could close this report.

I do not mean to close it.

We already have several passes for geometry processing: mesh-clasterization, BVH-build(for physics) and BVH for RT.
Adding one more will be too much, but we can considered to interleave polygon de-duplication with one of existing passes.

And as usual, since gain is quite small this work will fall behind in favor of other stuff

A nicely reachable one is in Khorinis at the entrance to the barracks.
