MAMEWorld Forums - EmuChat - MAME HLSL

Hi all,

I recently moved from Windows to Linux. When trying to apply my MAME HLSL config on the Linux version, I am getting very different results.

Some of the shader parameters "Slider Controls" appear to have different value scales and ranges than in Windows.

For example, any of the "radial_convergence" values have a greatly amplified impact on the video. Modifying even by the smallest 0.1 value increment, which in Windows would be almost visually inperceptable (ie. offset the effect by a single pixel) instead has the following effect in Linux where the impact on the video is massive:

radial_convergence_x incremeneted by + 0.1:

Another video parameter, "Signal Offset" allows setting a negative value in Windows MAME, but on Linux the minimal value is zero and so I cannot apply the required negative value that I use in the config to attain the desired HLSL effect.

I guess there is probably some way to modify the math/values in the shader files or something but I didnt know where to start and wondering if anyone else has experiencing this issue?

I have tweaked my HLSL settings for years and have it perfected to my preferences and really eager to replicate it on Linux so if anyone had any suggestions I would greatly apprecaite it.

Out of interest, my final base (Windows) HLSL parameters are as follows and many thanks must go to the folks over at this mammoth forum post as I used a lot of the tweaks there as my starting point:
