Utopia Must Fall is great base-defense arcade shooter, easily one of my favourites that I played earlier this year and soon Steam Deck players will enjoy it.
More about it: Utopia Must Fall is a vector-flavored base-defending arcade shooter with rapid progression, procedurally generated attack waves and enough upgrade variety to suit both the defensive or aggressive player. It incorporates elements from tower defense, roguelikes and beyond, all neatly packaged into a laser-sharp bullet-purgatory arcade frenzy!
Writing about the update developers Pixeljam said "This update is a little different, as it focuses mainly on performance, graphics options, Steam Deck support, quality-of-life features, and lots of small additions and improvements" and that it was a "necessary update to pave the way for new content, which will be much easier to add now that we have these others things out of the way" - so there's even more to come.
For the Steam Deck they added controller support, and suggest you use the latest Proton 10 Beta. And you'll want to set "Disable Frame Limit" in the Steam Deck performance settings for it to v-sync properly.
Aside from that there's some other major changes to improve it including:
- Entirely new vector rendering system built from scratch
- Around 6x faster raw line drawing performance!
- Custom effect shader pipeline
- Multisample antialiasing up to 4x
- Variable pixel density up to 2.0x
- Improved system loop timing: legacy 'delta' timing mode removed
- Significant optimisation gains in collision detection, entity management, memory traffic, etc.
- More accurate collision detection
- After one launch into fullscreen via the windowed intro, the app will auto launch into fullscreen next time (unless the app is set to windowed again while running and then quit)
- New CRT effects (bezel reflections, barrel distortion, phosphor trails, new overlays)
- New graphics options: aperture (beam width), dwell (corner sharpness)
- Manual viewport scaling options
- New audio mix: sound effects, aux reverb and speech generator are dynamics compressed in a dedicated bus (pre-fader), music channels are no longer affected by global dynamics compression
- Experimental X/Y oscilloscope audio renderer (requires high sample-rate DC-coupled audio interface, not practical for or enabled in UMF yet)
Numerous other smaller details on the Beta and all changes in the Steam post.
