kd-11 c38ca21a81 rsx: Round up 8-bit ROP output on NVIDIA cards 
- NV GPUs have a tendancy to be off by a very small margin, breaking rendering when greaterThan/lessThan checks are used.
- NOTE: Currently this setting is using the sRGB flag which indicates 8-bit output.
  Only one game is currently known to care about this behaviour so this is good enough for now.

kd-11 e1d1d16227 gl: Alias register binding points a bit 
- While aliasing is easy to break, it allows outdated hw to run
 2021-10-10 16:15:28 +03:00
kd-11 20bd723e7c rsx: Add floor workaround for GPUs with rounding issues 
- Mainly affects nvidia where x/w * w can sometimes return a value smaller than x.
  In such conditions, floor(x) will return x-1 if x is an integer which is horribly wrong and exaggerates minor precision drift to great proportions.

kd-11 39815801aa rsx: Implement proper decoding for some obscure fragment instructions 
PK4UBG and UP4UBG were dropped from the NV_fragment_program spec in 2002.
Not much information about them remains but seems pretty straightforward.
 2021-06-05 21:02:14 +03:00

Megamouse 838cbe1840 tiny include fix 2021-01-11 13:04:46 +03:00
kd-11 a96b4412d3 rsx: Do not rely on program env state, instead, always use program ucode analysis results when doing codegen 
- Some things can be present in program env but not ucode state
  e.g A texture can be active and bound in a redirected manner but not actually be used in ucode
  In such a case, only the ucode analysis or decompilation can decide whether to inject decoding routines

kd-11 7553429130 gl: Thread shader source compilation dispatch 
- glCompileShader is in itself much slower than anticipated
 2020-11-21 20:43:15 +03:00
kd-11 f4ec28d932 rsx: Merge instruction expand flag with the other sign expand flags 
- Avoids double expansion when both the exp_tex flag is set AND the texture also is sampled as signed
- Should fix missing eyeballs in Mass Effect 1 with the previous sign expansion fix

kd-11 0b2f9f0f17 rsx: Add support for delayed shader discard. 
- Noticed a glitch on AMD hw and windows drivers where discard seems to affect entire 4x4 cells.
- Dead fragments (outside the primitive boundary) could have their discards trigger as they do not have proper access to variables.
- This introduces dead fragments along triangle edges, causing a diagonal line pattern across the screen that is very annoying.

kd-11 901942f24a rsx: Replace pointless f32[4] restriction on texture parameters. 
- Use a struct instead to improve readability and remove pointless OpBitCast
 2019-10-22 13:44:49 +03:00
kd-11 3c44065684 gl: Fix copypasta 
- MSAA is still unimplemented in OGL
 2019-10-20 21:38:40 +03:00
kd-11 7aed9c3f13 gl: Add missing input declarations for 2-sided lighting 2019-09-30 21:52:43 +03:00
kd-11 eed32cf3a4 rsx: Decompiler fixups and improvements 
- Fix 2D coordinate sampling of W coordinate.
  W is actually HPOS.w and not 1. Z is however always 0.
- Optimize register usage a bit
  Disassembling compiled SPV shows that global declaration results in less ops than using inout modifiers. Modifiers generate extra mov instructions.

kd-11 3e28e4b1e0 rsx/decompiler: Restructure program register behavior 
- Fix reading of varying registers in FP
  Different registers have different behavior
- Always write to varying registers. If a register is not written to, it is initialized to (0, 0, 0, 1)
- Reimplements two-sided lighting correctly without hacks
- Also bumps shader cache version
 2019-08-26 20:03:31 +03:00
kd-11 6be7c58fa4 glsl: Refactoring, cleanup and optimizations 
- Avoid generating unused code
- Reduce GPR usage in emitted code
 2019-06-25 20:50:54 +03:00
Lassi Hämäläinen c963c51a60 Remove unnecessary header includes 
- Manually removed lot of unneeded #includes to clean code and reduce
  compilation time
- Reordered some of the #includes to be in more logical order
