Sharp-Bilinear Shaders for Retroarch\ (0 comments)

Here's hoping you'll consider porting scale2x or rsn8887's sharp-billinear-simple (cg vertex and fragment / glsl). 🙏

Tested it with "sharp-bilinear-2x-prescale" shader shader (you have to download it from github on ArkOS ( https://github.com/rsn8887/Sharp-Bilinear-Shaders/releases )), same performance as described above (with shaders untested (as in deactivated.. ;) )).

Sharp bilinear simple you’ll find it in the sharp folder when loading a shader preset, I usually go with the 2x prescale version. This post by the developer explains what it is and why you’d wanna use it.

I personally still like the RetroPie setup the best. It has some quirks, but I think it's mostly a sensibly configured solution and there's plenty of community knowledge / help out there. Maybe it's just familiarity bias, but after many hours of poking around in it and tweaking stuff I can't say I dislike it.

IMHO worst part of the out-of-the-box experience with RetroPie is that everything is configured for maximum performance, which kinda means worst latency. The input lag is astronomical if you're used to original hardware / FPGA emulation / CRTs or zero-lag scalers etc. You can get it to very acceptable levels for many systems, but you have to know which settings to change.

Here are the notes I took when configuring and tuning my setup:

They're for a Pi 3B that's setup for output on a CRT TV, but like 90% should apply to a Pi4 on an HDTV.

Shaders are always a personal taste thing. Those posted here certainly get the as sharp as possible without shimmering, blurring, borders or wrong aspect look right, but there are other options if you want the CRT look.
