      Thanks for exploring this one - I assumed that my RetroPie upgrade had overwritten my retroarch.cfg files. The advice here has fixed my missing shaders in my install (a 64-bit Raspberry Pi OS install).

      Running and updating the setup script, navigating
      P Manage packages
      C Core
      43 Retroarch
      U Re-install (from source)
      has fixed the problem for me.

      Removing the curvature removes the morié pattern completely:

      Which is a shame...I really love that curving for the old school feel, especially for the 2600 where there weren't any Trinitron sets yet!

      @smartroad said in No shader parameters?:

      I'm guessing I have missed something or this just isn't supported with this version?

      It should be supported, but I don't see any dotmask.glslp (preset), just the shader itself (.glsl) - are you sure you're not loading another preset, that includes the dotmask shader, and has parameters to adjust ?

      as far as i recall the shader preset includes bilinear on/off, so you should not touch it and let the preset decide

      neurocrash

      @neurocrash Just in case anyone else gets the same idea, I was able to run Dos Vectrex Emulator in Retropie Dosbox, and while it looks great, it is far too slow on my Raspberry Pi 3. I think it runs at about 50% of the original speed.

      Cheers

      The crt-mattias and crt-geom are way too demanding for a Raspberry Pi, they're not installed by default on the Pi - only on a PC installation.

      Thank you for sharing your solution. The question remains why the save function from the shaders menu doesn't work for you and me, although the RGUI says that it did save the settings.

      If you want to dive deeper into the "failed saving config" error, please open another topic about it (for tidiness and all), start any game from that core with verbose logging via the Runcommand menu, try to (fail to) save the config, and post the contents of /dev/shm/runcommand.log in a code block in your new topic. 🙂

      @TimZett said in General questions on applying shaders (video filters):

      The vertical shader I just took for testing purpose, because it shows something significant ;-)
      Currently I'm using the bilinear (blur) shader since I find the Atari games in all emulators way too blocky.

      I use CRT + smoother for everything. Then again, the only stuff I really play on RetroPie is SNES and PS1.

      @TimZett I think @dankcushions posted a link (maybe in another topic) to the Shader docs in Retropie's documentation - https://retropie.org.uk/docs/Shaders-and-Smoothing/.

      We don't offer support for 3rd party images, especially the ones loaded with ROMs. If you want support here in the forum, start with the RetroPie provided image from retropie.org.uk/download. Otherwise, contact the author of the image and ask for support.

      very cool! the libretro forum's images show the difference more clearly. it would be cool to benchmark this, crt-pi, and the zfast crt shader.

      @trekdrop It's not possible at the moment. The shaders are only available in RetroArch, so they're applied when a game starts.

      thelostsoul

      Ok, so after I wanted play some games now, I realized the bottom part of the lr-snes9x games are always black. I can't say how many rows, but maybe 10th. The other sides are all on the edge of screen and Emulation Station is shawn correct, lr-nestopia too. Is there a setting I miss? The strange thing is, in RetroArch menu the whole screen is used. The emulator makes the image of game smaller and shows a black bottom border only.

      EDIT: Ok so, after quick testing, it happens also in PC Engine, but not the other emulators.
