Unlike current FSR, FSR4 will only work on new AMD chips using the RDNA4 architecture. AMD is claiming pretty major improvements over the current FSR3 results, but it being hardware specific means that it won’t directly benefit the current steam deck. However it could be one of significant hardware improvements that we would see in a steam deck 2.
I’m done with AI upscaling. We’ve literally went back in time. New cards release advertising 4K only with upscaling when we had 4K on the high end back in 2018
AI upscaling is cool when it lets older and weaker hardware play modern games, but I don’t like the wave of modern poorly optimized games that use it as a crutch to be playable at all.
It’s mostly UE5 games, but now we also have RE engine performing terribly on MH Wilds. There’s also games like Indiana Jones that now have mandatory ray tracing for all the lighting.
