You can for instance increase Vibrance for a more fantasy-like look, or use Desaturate or Sepia to give the game a more eerie feeling. More advanced settings include color curves and tone mapping, which can be used to change the mood of the game. It is a bit complex and complicated to use, since you have to make some settings. When manually disabling the iGPU, RA works as intended. RetroArch is a single emulator with which to play the games of any old console. Sharpening can be particularly useful in games with “muddy” textures like the Dishonored or Bioshock series. Description When Vulkan is chosen as the video driver, RetroArch attempts to use the integrated GPU instead of the dedicated one and gets stuck. Other interesting options are HDR which tries to mimic real HDR, and LUMASHARPEN which can be used to sharpen the detail of characters and items. You can turn on FXAA or SMAA Anti-aliasing by typing a boolean value (1 for “on”, 0 for “off”), but make sure to turn Anti-aliasing off in the game visual settings, as SweetFX will replace it. Opening the SweetFX_Settings.txt file will reveal a host of options. You can personalize your games further by creating your own SweetFX profiles, or editing existing ones. After installing the SweetFX preset, and using the in-built SMAA, performance improved to 58 fps average, along with a boost in visual quality. With the game settings set to Ultra and TXAA turned on, we averaged 52.3 fps. The preset used was “| ULTRA TXAA | NO BLUR” by Sp00ky. By disabling the Anti-aliasing processing in-game and using SweetFX’s SMAA instead, in conjunction with a sharpening filter, we can achieve not only better graphics but also improved performance.
Some games that are poorly optimized like Dishonored 2 can greatly benefit from certain SweetFX profiles.
