1ec454197a HLSL Updates: [Ryan Holtz, Bat Country Entertainment, austere] 
- Reworked default shadow mask settings, eliminating rainbow banding and matching reference shots more closely
- Moved color power to occur after shadow mask, as it is intended to simulate nonlinear phosphor response
- Added a variable-width notch filter to the Y channel in NTSC post-processing, eliminating luma banding on e.g. CoCo 2 and Apple II

771b77142f Fix for performance regression and slider regression in HLSL, also re-enabling pixel prescaling in yiq_encode.fx. No whatsnew. 2011-06-03 14:38:59 +00:00

796e691522 HLSL Updates: [Ryan Holtz, Bat Country Entertainment, austere, SoltanGris42] 
- Added the ability to render screenshots at arbitrary resolutions.
- Added the ability to record AVI videos (albeit with no audio) at arbitrary resolutions.
- Added a 43-tap-wide FIR-based NTSC filter with tunable Y, I and Q frequency response.
- Updated scanlines to have a user-tunable pixel-height ratio in addition to the current screen-height ratio.
- Fixed a VRAM leak that was causing many dynamic-resolution drivers to run out of memory mid-run.

e97aa6b56d Internal HLSL cleanup - removed aux texcoords, restored software vertex processing due to low-end cards not doing hardware vertex processing, removed unnecessary tristrip->trilist splitting. Restores D3D functionality on integrated chipsets and marginal cards. [Ryan Holtz, Ashura-X] 2011-05-24 18:28:54 +00:00

fd7a110eba HLSL Updates [Ryan Holtz, Bat Country Entertainment] 
- Re-worked render target handling to align pixels better, reducing unintentional blurring
- Made major fixes to CVBS simulation, significantly increasing color saturation

cfd6731fa8 HLSL Post-Processing Updates: [Ryan Holtz, Bat Country Entertainment, cgwg] 
- The defocus pass is now switched off when defocus_x and defocus_y are zero, allowing finer-grained performance tuning.
- Removed YIQ convolution from the main color-convolution shader and replaced it with a full composite encode/decode pass. This is slower, but looks amazing(ly like a terrible TV) and can be turned off.
- More authentic NTSC dot crawl and bandwidth limiting.
