[d3d8] Railroad Tycoon 3 - zoomed in terrain shuffle #4114

Open WinterSnowfall opened 4 months ago

WinterSnowfall commented 4 months ago

This is going to be a rather hard one to describe, so I've captured a video. The TLDR of it is that when scrolling through some of the closest zoom levels on the game map, the terrain textures sort of shuffle around in a crazy dance.

I've captured a trace, but since the game does "wonderful" things with buffers, apitrace has mostly caught garbage. The issue can be seen in the trace as well though, among the madness.

Could be an ANV bug, but on Intel the game doesn't render geometry properly at all and ultimately crashes with:

/usr/i686-w64-mingw32/include/c++/13.1.0/array:202: constexpr std::array<_Tp, _Nm>::value_type& std::array<_Tp, _Nm>::operator[](size_type) [with _Tp = dxvk::DxsoSemantic; unsigned int _Nm = 32; reference = dxvk::DxsoSemantic&; size_type = unsigned int]: Assertion '__n < this->size()' failed.

New set of logs, collected with a debug build from @K0bin: RT3.log

Edit: Second set of more verbose logs: RT3.log

We just fixed the Intel crash at least.

Apparently it crashes on ANV inside vkCreateGraphicsPipeline now.

There are a bunch of validation errors that need to get investigated. RT3 validation errors.txt
