Philip Rebohle 11f08c7dea
[dxbc] Declare vertex positions as invariant 
Otherwise, games relying on different vertex shaders to produce
the same numerical results may suffer from Z-fighting issues.

Fixes #1364.

[dxbc] Remove old constant buffer range check 2019-10-28 17:52:50 +01:00
Philip Rebohle 3d213efe53
[dxbc] Use SSBOs for dynamically indexed constant buffers if needed 
SSBOs are tightly bound-checked on all Nvidia GPUs, so this allows for
a more accurate workaround for games relying on OOB access behaviour.

[dxbc] Use OpDemoteToHelperInvocationEXT for discards if supported 2019-07-11 19:33:17 +02:00
Philip Rebohle d755b18ccb
[dxbc] Repurpose useRawSsbo option 
Basically, abuse the minSsboAlignment property to convince the
compiler to always/never emit raw SSBOs for raw and structured
buffers, and use the actual device limit by default.

[dxbc] Always use raw storage buffers if alignment requirements are met 2019-06-11 20:20:40 +02:00
Philip Rebohle d94d89c3ef
[dxbc] Add option to use subgroup ops for atomic counter operations 
This can greatly reduce the number of atomic operations when using
append/consume buffers.
 2019-05-15 18:49:02 +02:00
Philip Rebohle 9b99c55a2e
[dxbc] Implement optional constant buffer range check 2019-04-05 20:56:29 +02:00
Philip Rebohle 0326258829 [dxbc] Use SDiv instead of ShiftRightLogical for index calc on Nvidia 
Reportedly fixes Resident Evil 2 and Devil May Cry 5 on Nvidia.

[dxbc] Only emit depth clamp in fragment shader if necessary 
We don't need this if the depth clip extension is supported
by the driver.
 2019-02-19 14:27:21 +01:00
Philip Rebohle c0b325b483
[dxbc] Add option to enable strict sm4-compliat division 
SM4 is defined to return the first source operand if the divisor is zero.
Windows drivers don't do this by default, so we shouldn't do it either.
 2019-02-05 21:08:13 +01:00
Philip Rebohle 48548eb894
[dxbc] Add useRawSsbo option 
ENabled when we can replace texel buffers for raw and structured
buffers with raw SSBOs.

Philip Rebohle a75c596132
[d3d11] Add config option to enable TGSM initialization 2018-11-23 16:12:02 +01:00
Philip Rebohle ea5f11d091
[dxbc] Implement function to clear thread-group shared memory 
Can be enabled in case a game reads undefined data from TGSM.

[dxbc] Use clustered subgroup operations on supported hardware 2018-11-21 11:17:09 +01:00
Philip Rebohle 4f76b89941
[dxbc] Use subgroup operations for early discard 
Can improve performance in some complex fragment shaders.

[dxbc] Remove DeferKill flag 
This behaviour is correct, and needs to be enabled by default.
 2018-11-21 11:17:09 +01:00
Philip Rebohle 05856e836b
[d3d11] Don't enable StorageImageReadWithoutFormat feature for FL11_0 
We don't really need this, although it might be useful in the future.
 2018-11-10 11:34:23 +01:00
Philip Rebohle bd03225c14
[dxbc] Refactor DxbcOptions 
A bit mask isn't good enough going forward, and we also don't
need application-specific options for now.

[dxbc] Remove workarounds for the old Nvidia shader compiler 2018-06-12 22:13:53 +02:00

[dxbc] Remove Tex2D -> Tex2DArray workaround 2018-05-24 11:49:12 +02:00
Philip Rebohle 01147492d5 [dxbc] Implemented Texture2D -> Texture2DArray mapping as a knob 
Doing this for all applications is not necessary and degrades
performance in some cases.
 2018-04-23 00:46:27 +02:00
Philip Rebohle e53cb72e39 [dxbc] Make DxbcOptions a set of flags 
This allows for game-specific workarounds and driver-specific
workarounds to be applied in an easier fashion.

gets too big.
