A lot of AAA games require some setting tweaks, but most will run decently at 30fps. Main exceptions are UE5 games, games with mandatory ray tracing for lighting (id’s new engine), and MH Wilds for some reason (every other game on the RE engine runs great afaik, except for Wilds).
UE5 games partially suffer from mandatory ray tracing as well (lumens), but even with mods disabling lumens, they still are hit or miss on performance. There’s a mesa update in the pipeline that massively improves ray tracing performance on the deck which will help the non-modded performance of UE5 games and all other mandatory ray tracing games, but I don’t know when it will actually reach the deck through official update channels.














It’s possibly a damaged cable, they’re pretty delicate.
Also, are you sure you bought the same type of replacement audio board? The original LCD decks used two ribbon cables to connect the audio board, while the revised design LCDs and OLEDs use only a single cable. If you bought the wrong audio board it may have a secondary unused ribbon connector, and won’t work with just the single ribbon cable of the newer decks.
