Based on request we are providing a Path Tracing Benchmark in 16_RayTracing. It allows you to compare the performance of three platforms:
- Windows with DirectX 12 DXR
- Windows with Vulkan RTX
- Linux with Vulkan RTX
We believe that every benchmarking tool should be open-source, so that everyone can see what the source code is doing. We will extend this benchmark to the non-public platforms we support to compare the PC performance with console performance.
The benchmark comes with batch files for all three platforms. Each run generates a HTML output file from the microprofiler that is integrated in TF. The default number of iterations is 64 but you can adjust that. There is a Readme file in the 16_RayTracing folder that describes the options.
Windows DirectX 12 DXR, GeForce RTX 2070 Super, 3840x1600, NVIDIA Driver 441.99
Windows Vulkan RTX, GeForce RTX 2070 Super, 3840x1600, NVIDIA Driver 441.99
Linux Vulkan RTX, Geforce RTX 2060, 1920x1080, NVIDIA Driver 435.21
We will adjust the output of the benchmark to what users request.
- With this release we also aligned the whole renderer interface better to 64 byte CPU cache lines. We trimmed down all the structs substantially and removed many. This is a breaking change for the renderer interface and a major change to the whole code base.
- DirectX 12
- D3D12 Memory Allocator: we are using now AMD's D3D12 memory allocator for DirectX after having used the Vulkan equivalent for more than two years. We also extended it to support Multi-GPU.
- We upgraded to the latest dxgi factory interface in DirectX 12
- Microprofiler: because we need the microprofiler to offer the QA department help in reporting performance problems for some of the games that will be shipping with TF (and the benchmark mentioned above), we did another pass on its functionality and ease of use, especially on console platforms. The idea is that QA can quickly and easily store a screenshot or HTML file in a bug report. This is still work in progress and with every shipping game will probably be improved.
- Now that GDC 2020 was postponed, we will also postpone our GDC related activities. The user meeting and our GDC talk will be postponed until the next GDC happens. If there is a need we can also do a user meeting in an online conference room or in Discord in a private area. Let us know.
- Renamed CustomMiddleware to Custom-Middleware back ...
