Holy cow, that FSR 2.1 article has proven to be quite a hit. It’s already my third most-viewed article on the entire site. As such I wanted to follow up and actually put FSR 2.1 to the test on Steam Deck, to see whether or not it could live up to the claims I previously brought out. I’m again using Kena: Bridge of Spirits as the test sample. The only other game I have in my library that I can test FSR 2.

You might have heard about NVIDIA’s Deep Learning Super Sampling (DLSS). While it may be advantagous for achieving higher framerates at lower resolutions, while still retaining most of the same graphics quality, the downside is that the technology is essentially locked behind a paywall: you need to have a RTX GPU in order to use it. But you don’t need to pay an arm and a leg for said GPU. Fortunately for us, we can make use of an alternate technology that offers much of the same capabilities: FSR 2.
