In-Game GPU Profiling for DirectX 12 Using SetBackgroundProcessingMode

Nvidia

JULY 10, 2023

Still, even with GPU Boost disabled using the DX12 SetStablePowerState API, GPU timings measured in-game may still change unexpectedly from run to run, or from frame to frame. One factor to consider is whether background driver optimizations were engaged and when their resulting optimized shaders were deployed.

Implementing Path Tracing in ‘Justice’: An Interview with Dinggen Zhan of NetEase

Nvidia

OCTOBER 4, 2022

New technologies generally bring new problems, and the debugging process is particularly more difficult. Fortunately, NVIDIA has upgraded the NVIDIA Nsight debugging tool in time, making it an easier process for development work. Debugging costs us significant time. From beginning to end, it took us about five to six months.

Godot 3's renderer design explained

Mircosoft Game Dev

SEPTEMBER 23, 2017

Godot uses a considerably different approach to rendering (and rendering abstraction) than other, popular, game engines. For example: On GLES3+ we can use UBOs to optimize shader parameters. As for DirectX12, it's only relevant for Windows/UWP, so there is no strong incentive for us to support it as a cross-platform engine.
