d912pxy is a way to make games that use DirectX 9 use DirectX 12 instead, without changing any game code.
This is specifically designed for Guild Wars 2. You can try to use it with other games; it might work.
This project is in beta. Expect some bugs, crashes, hangs, stalls and some other fun stuff.
WARNING: USE OF THIS SOFTWARE IS ENTIRELY AT YOUR OWN RISK!
Profiling shows that the API overhead for d912pxy is up to 86% (r255,custom config) less than that of plain DirectX9. Real performance differs based on the scene and the hardware.
Benchmarking results on i7-7700/GTX960:
(running Mistlock Sanctuary)
@6.3k batches, all max, 1080p, v0.9.5.8a
dx9
min FPS: 5.5
max FPS: 21.5
dx12
min FPS: 17.6
max FPS: 26.6
boost:
min FPS: +220%
max FPS: +23%
(1h fractal runs)
@all max, 1080p, v0.9.6.2a
16.4% to 2.5% less frame time
calculated based on API profiling & metrics data
This is affected by performance recording, and should be better in normal situations
