I finally found an N64 shader config that does a great job at covering up the often-horrible pixellation on HUD and font elements when upscaling. In this case I run at 4x resolution on a 1080p screen.
This is a combination of the 4xSoft and Lottes CRT shader (my favourite CRT shader - doesn’t cause dark scanlines like most of the others). Both the softening and the NTSC effect contribute to masking the deep pixellation, but you still get to appreciate the high-res 3D.
shaders = “3” shader0 = “C:\DATA\Games\RetroArch\shaders\shaders_glsl\xsoft\shaders/4xsoft.glsl” filter_linear0 = “true” wrap_mode0 = “clamp_to_border” mipmap_input0 = “false” alias0 = “” float_framebuffer0 = “false” srgb_framebuffer0 = “false” scale_type_x0 = “source” scale_x0 = “2.000000” scale_type_y0 = “source” scale_y0 = “2.000000” shader1 = “C:\DATA\Games\RetroArch\shaders\shaders_glsl\xsoft…/stock.glsl” filter_linear1 = “true” wrap_mode1 = “clamp_to_border” mipmap_input1 = “false” alias1 = “” float_framebuffer1 = “false” srgb_framebuffer1 = “false” shader2 = “C:\DATA\Games\RetroArch\shaders\shaders_glsl\crt\shaders\crt-lottes.glsl” wrap_mode2 = “clamp_to_border” mipmap_input2 = “false” alias2 = “” float_framebuffer2 = “false” srgb_framebuffer2 = “false” parameters = “hardScan;hardPix;warpX;warpY;maskDark;maskLight;brightboost” hardScan = “-8.000000” hardPix = “-3.000000” warpX = “0.000000” warpY = “0.000000” maskDark = “0.500000” maskLight = “1.500000” brightboost = “1.000000”
Here’s an example image from Wave Race, which has a horribly pixellated HUD.
I, myself tryed several Shader Configs but always end up to choose none of them and just play on highest resolution. Maybe im too dumb for that. On 2D Games i always go for XBRz (Benchmark on Super Metroid). On 3D i struggle between performace and image quality -.-
