A shader that specifically tries to emulate Sony PVM's with an aperture grille screen but with full brightness.
|
|
|
|
The novel thing about this shader is that it transforms the image output by the 'console/arcade/computer' into HDR space first i.e brightens it first and then applies
|
|
an aperture grille afterwards which is kind of what a CRT would actually do - its kind of a kin to the electron beam (but nothing like it lol).
|
|
|
|
My DisplayHDR 600 monitor does seem to get reasonably close to the brightness of my PVM - its not quite there but its close. I think DisplayHDR 1000 and above will be able to match.
|
|
|
|
Currently defaults towards a Sony PVM 2730QM a reasonably old mid 1980's 27" 600TVL pro monitor.
|
|
|
|
To use:
|
|
Please Enable HDR in RetroArch 1.10+
|
|
|
|
NOTE: when this shader is envoked the Contrast, Peak Luminance and Paper White Luminance in the HDR menu do nothing instead set those values through the shader parameters
|
|
|
|
For this shader set Paper White Luminance to above 700 and Peak Luminance to the peak luminance of your monitor.
|
|
|
|
Also try to use a integer scaling - its just better - overscaling is fine/great.
|
|
|
|
This shader doesn't do any geometry warping or bouncing of light around inside the screen - I think these effects just add unwanted noise, I know people disagree. Please feel free to make you own and add them
|
|
|
|
Works only with the D3D11/D3D12/Vulkan drivers currently
|
|
|
|
THIS SHADER DOES NOT SUPPORT WRGB OLED (Due to the sub pixel layout of WRGB - QD-OLED or LCD (and variants thereof screens are fine)
