  • 89f8f0d71f FSR 2.3.4/3.1.5 update: Fix for possible negative rcas output. fsr3.1.4 Nico de Poel 2025-08-23 13:05:59 +0200
  • c31c462f7f Fixed Metal not getting compiled with texture array support, which broke HDRP support. Nico de Poel 2025-08-23 12:31:16 +0200

  • ef8a19887b (FSR3) Clear new locks buffer ahead of the frame instead of at the end of the Accumulate pass. This makes more sense with NewLocks being an aliasable (temp RT) resource, and it avoids reading and writing to the same texture in the Accumulate pass. Nico de Poel 2025-05-11 12:28:13 +0200
  • 5bb38aa76d (FSR2) Clear new locks buffer ahead of the frame instead of at the end of the Accumulate pass.

  • 76d0ee5425 Changed all dispatch descriptions into structs, renamed some fields, cleaned up some unused code. Changing to lowercase field names for public struct members now, which follows the C# naming conventions.

Nico de Poel 2024-07-27 23:08:56 +0200
