- Take viewport offset into account when applying window transforms.
This is necessary because gl_FragCoord is based on the framebuffer and not the viewport.
- Allows sections reclaimed by the surface store due to overlap/inheritance to be identified and removed.
- Additionally, potentially lowers the number of flushes required per block with multiple overlaps improving efficiency and theoretically performance.
Allow x30 times the speed of vblank rate + clocks scale of original PS3.
In theory a 60 fps limit game which scales frame limit perfectly with vblank rate can be played at up to 1800 fps with this change.
And:
* Fixed lv2 sleep with Clocks Scaling
* Make these settings dynamicaly adjustable.
* Avoid code duplication
- Reject writes to RTT if the source data is of unknown origin.
non-RTT data and only 1 line in length is suspicious and often GPU data like programs or other rendering inputs.
- Attempt to identify blit operations that will be flushed immediately
after and just do them on CPU instead if the transformation is trivial.
- If only a single blit section is contributing to an atlas merge op, the
threshold should be 100%. The only acceptable result here is a
truncation.
- Raise passing 'score' from 50% to 90% to filter out very incomplete
merge operations.
- Catch unfit sections passing the match test; possible for blit_dst
data but will likely be always harmless. Disabled in release builds by default.
- Some games use texture semaphore for zcull sync which is rather bizzare.
However, it works on realhw as the depth test happens before fragment shader completion
- Due to the high performance penalty incurred by this act, this
behavior is only enabled by the "strict rendering mode" option.
- Adds support for partial (letterboxed) source images by taking insets
into account.
- Bugfix for potential access violation when capturing screenshot on
vulkan
- Adds the same optimization/simplification steps to complex image
transfer routines. Whenever possible, multi-step transfers are collapsed
into a single operation.
- Avoid double transfers where a transfer to a temp image is done
without scaling and then a secondary transfer follows. Combines the two
steps into one whenever possible which can significantly alleviate
bandwidth problems at higher resolutions. Significant speedup, upto 90%
in some cases (PDF, PDF2)
- Interpolating floats is not the same as interpolating their bits!
Use integer format to interpolate linearly for D32F formats instead of using R32F as intermediary
