I’ve been playing with Mupen64Plus Next on my Steam Deck, with both RDP and RSP plugins set to Parallell-RDP, performance is surprisingly good! But I have a question regarding the resolution: it seems that Parallell at 1x resolution displays games at 640x480, but I thought games were rendered at 320x240 on the original hardware? Due to the fact that the game renders at 640x480, I cannot use Integer scaling since the Steam Deck screen resolution is 1280x800, it displays the game at 1x so 640x480 and the game window is very small. If I disable Integer scaling, I get uneven scanlines so that’s not an option.
I would like to be able to render the game at 320x240 (0.5x resolution?) and use integer scaling so that it would be displayed at 960x720 which would be perfect for the Steam Deck’s screen.
