Bug ID: 56167
           Summary: Unigine Heaven 4.0 DX11 benchmark performance loss on
                    Nvidia gpu
           Product: Wine
           Version: 7.2
          Hardware: x86-64
               URL: https://assets.unigine.com/d/Unigine_Heaven-4.0.exe
                OS: Linux

          Keywords: download, performance, regression
          Severity: normal
          Priority: P2

   Regression SHA1: 7c844cd3c9c465bdeaf3d98d6da5f2f5e460e650
      Distribution: ArchLinux

I'm filing this bug report because the proposed patch by Zeb Figura from bug
#54223 doesn't resolve the performance regression for me in Unigine Heaven DX11
benchmark:
https://gitlab.winehq.org/wine/wine/-/merge_requests/4821

The problem: with current Wine (wine-9.0-rc4-25-g44aa651dc54) there is a
roughly 30% performance drop in the DX11 benchmark compared to that of
Wine-7.1.
The DX9 and OpenGL benchmarks are not affected.

The first commit where the problem appeared for me:
commit 7c844cd3c9c465bdeaf3d98d6da5f2f5e460e650
wined3d: Use the chunk allocator for GL indirect draw buffers.

The settings I'm using in Unigine Heaven 4.0:
Preset: custom
API: DirectX 11
Quality: Low
Tesselation: Disabled
Stereo 3D: disabled
Multi-Monitor: disabled
Anti-aliasing: Off
Full Screen: unchecked
Resolution: 1280X720

This is the result of the DX11 benchmark in wine-9.0-rc4-25-g44aa651dc54:
FPS: 126
Score: 3174
Min FPS: 11.9
Max FPS: 362.3

The benchmark with commit 7c844cd3^:
FPS: 175
Score: 4390
Min FPS: 10.9
Max FPS: 362.9

Tested and reproduced with the following Nvidia drivers:
470.223.02 (legacy branch)
535.43.22 (Vulkan dev)
545.29.06

Please let me know if I should provide debug logs or further tests.

About my current system:
Kernel: Linux 6.6.10-zen1-1-zen [x86_64] @ Arch Linux
X.Org X Server 1.21.1.10
XFCE 4.18 (compositor disabled)
GPU: NVIDIA GeForce GTX 1660 SUPER/PCIe/SSE2 (6 GB)
Memory: 32 GB
CPU: AMD Ryzen 5 5600X 6-Core Processor
