I’ve been waiting for this update for months, this beta update includes an important update to Mesa that includes significant improvements to ray tracing performance. My understanding is that Unreal Engine 5 games especially should see improvements from this update.
It also includes VRAM management improvements, which will help on demanding games.
Overall this update will hopefully really help the deck with the games it struggles most with. I’m very interested in seeing what kind of benchmark improvements it brings.
Here’s an older article on the ray tracing improvements that includes some fps benchmarks showing the improvements. Oblivion Remastered saw 24% increase in fps, with some other games getting as much as a 74% increase in fps. I don’t expect to see gains that large in most games on the Deck, but it will certainly help.
