• DLSS should now work in supported games in combination with dxvk-nvapi.
• Optimized D3D9 shader constants by relying on VK_EXT_robustness2 and removed the old app options for games using software vertex processing. (#2282)
• Added an option for more accurate emulation of D3D9 floating point behaviour and enabled that by default for a bunch of games. (#2294, #2359). 
• Fixed a DXGI issue which would sometimes cause games to fail to enter fullscreen mode on some displays that do not support low rates across all resolutions (#2395).
• Fixed an issue that would cause VRAM to not be utilized on RBAR-enabled Nvidia GPUs if the dxvk.shrinkNvidiaHvvHeap option is enabled (#2438).
• Enabled strict D3D9 float emulation by default on future versions of RADV. This may improve both accuracy and GPU-bound performance (PR #2448).
• Improved memory allocation behaviour. This may reduce memory usage especially in games that create multiple processes or D3D devices.

• Implemented non-seamless cube maps for D3D9 using the VK_EXT_non_seamless_cube_map extension if supported by the driver

• FIxed an issue with current versions of the Nvidia Vulkan developer driver not using its on-disk shader cache with DXVK
• Fixed an issue which would cause the state cache file to not be written properly
• Fixed an issue where incorrect barriers would be emitted for UAV rendering
• Fixed potential issues when using state caches that were created on a driver with a different feature set
• Fixed broken stencil resolves in D3D9
• Optimized performance of in-memory compression for SPIR-V shader code

• Added support for shared fences

Memory management improvements

In order to reduce the likelihood of running out of address space in 32-bit D3D9 games, DXVK will now use memory-mapped files to store shadow copies of textures. This allows us to unmap memory that is not being used by the game, thus freeing up significant amounts of address space, up to several hundred Megabytes. See PR #2663 for implementation details.

Note: This change does not affect 64-bit games since address space is not a concern there. It also does not affect D3D10 or D3D11 since resource uploads work differently in those APIs and are much more memory efficient.

Render target feedback loops

On drivers which support VK_EXT_attachment_feedback_loop_layout, reading from an active render target in D3D9 games is now properly supported, which previously caused rendering artifacts on newer AMD hardware and required driver-level workarounds. This affects a number of games, including GTA IV.

Alpha test improvements

The D3D9 alpha test implementation was changed to more closely match the behaviour of Nvidia's implementation, which fixes inaccuracies in various games. The d3d9.alphaTestWiggleRoom option was removed, and games that previously required this option should now work correctly by default.

Mejorado el compilador de shaders. Lo que se traduce en mayor rapidez y fluidez a la hora de hacer el cacheado de sombras.
