Steam: News

Official Steam on Chromebooks

  • It’s finally here! Kinda
  • There’s actually a pretty decent selection of games that are verified
  • If the iris mobile GPUs can actually do some decent punching, you could have an argument for a decent google gaming platform.
  • Hopefully at least on par with the deck.
  • That’s a list of $6/700 Chromebooks.
  • Core i5 or i7 processors, and at least 8GB of RAM.
  • Alpha means anything can break.
  • I look forward to seeing if ChromeOS Flex runs this, since my Chromebook proper apparently is falling out of support in June and only has a Celeron.


  • Fall in Labyrinth, King of Fighters XIII, Montaro, Metal Slug 2, Metal Slug 3, Double Dragon Trilogy, Baseball Stars 2, ATRI -My Dear Moments- are the new playable games
  • Lots of random little fixes
  • Update to the latest released vkd3d-proton
    • It was more of a wording update since the bleeding-edge Proton Experimental is pulling directly from git, so that’s the one that’s actually running the current development version.

Opt-in Annoyance

  • They are not crowdsourcing the compatibility testing process.
  • They are asking the crowd ™ if the system works and will alter things based on the feedback.
  • There is a difference.
  • I stopped Elden Crack since the battery was down to 10% after around 2 hours and it prompted me if I wished to contribute.
  • I answered yes since I figured that’d be fair to ask of the Early Access Adopter crowd.
  • Recaptcha for game compatibility isn’t a bad thing. That’s ultimately how you train these algorithms, so comparing against human control means they are actually trying

ChimeraOS Deck

  • They recommend a $800+ dollar Chromebook to use it.
  • Feature parity with Windows! Woot!
  • I gotta wonder what’s so special about the audio out here that everybody is having problems?

Steam consistency

  • This is not a collection of Steam over the years, nay.
  • This is Steam in 2022.
  • You can use them to carbon date when each UI element was last worked on.
  • You can tell this person doesn’t have a Deck because there’s quite a few missing there.
  • I guess there isn’t a consistency initiative at valve.
  • Either that or the dudes in that pod are just collecting paychecks
  • If it aint’ broke don’t fix it?

Steam: New Games

Dracula’s Revenge

  • Want some more OG Castlevania in your life after you played through all the bloodstained prequels and somehow got tired of listening to the excellent Rondo of Blood Soundtrack?
  • Five bucks for levels + hard mode seems decent, and the reviews seem to really like it
  • Apparently the soundtrack isn’t that great, but why fret when you can listen to rondo of blood again?
  • Looks like a DOS port of Vania.
  • They tacked on that mustache, damn.
  • Any Potato Linux is recommended.

Steam: Game Updates

RIP RetroArch Playtest

  • Uh oh, they’re centralizing deployment of an appimage on steam.
  • That’s a no no for some reason.
  • Nice of them to include instructions for moving your bits.
  • I guess the Playtest was working well enough that people didn’t really bother to get the full version.


Ham slicer?

  • Boy, we got a date for, something.
  • Smartphone, IntelDeck, top-heavy lappy?
  • I don’t look like a release date & pricing info for ARC.

Gamescope soon?

  • The main blocker is VK_EXT_image_drm_format_modifier but it is being worked
  • Apparently between the nvidia driver and gamescope, there are more than 1024 file descriptors per vkfence, which exceeds the defaults of most systems
    • That is exactly the default cap in quite a few distros.
  • This can apparently be handled by a rewrite of gamescope’s vkfence subsystem or on the nvidia driver end
  • Joshie already has something ready to push to see if it helps.
  • I look forward to moving this box to Wayland and getting my gamescope on, outside of the GabeGear.

DXVK 1.10.1

  • Initial support for shared resources.
  • Currently, only basic 2D texture sharing between D3D9 and D3D11 is supported when using DXVK for both APIs.
  • Speed bump for Ass Creed 3 and BF.
  • Fixed frame pacing issues on AMD with the latest GOW patch.


  • Very performant screen recording on linux.
  • Gotta patch your nvidia drivers if you don’t have a quadro or a tesla
    • You’d think nvidia would throw out that limitation given general availability, but fuck that noise give us money
  • The replay (and just recording in general) functionality being available without having to run full OBS in the background is probably the most welcome thing.
  • Does not work when using gtk client side decorations (such as on Pop OS).
  • No love for AMD, yet.
  • There is a plugin to use NvFBC with OBS, it works.
  • New nvenc is still in testing hell for OBS.

Open Golf

  • Browser based GILF
  • Linux & Android as well.
  • Even has a nifty in game editor.
  • Very simple mini-golf game built in C.
  • Comes with some GLSL code for your shading purposes.

Game: Hyperbolica
Devel: Code Parade
Engine: Unity
Price: £13.49 / $16.99 / $19.49

Wazzat: Hyperbolica is a whimsical Non-Euclidean adventure with mind-bending worlds full of games, puzzles, mazes, and secrets! Immerse yourself in reality-warping geometries where lines can never be parallel, horizons are curved, and space grows exponentially.

Mandatory Disclosure: Devs sent us keys



  • Clean bill of health on the working bits.
  • As you might have guessed it can do 60 @ 2160p.
  • Xclone picked up OOTB and the default keymap was sane.
  • Options for windowed and fullscreen.


  • This is a cool game mechanic demo but that’s where I’m at.
  • In my 59 minutes I have collected a map, walked in the woods, visited a cold wall, and failed to find the kitchen in a restaurant.
  • Oh, I found a watch in a bottle at the beach as well.
  • Aaaand was bounced from a museum because I was not on the guest list.
  • I did spend some time bouncing on the trampoline.
  • That’s where I’m at.
  • 59 minutes in and waiting for the “oh shit” clever moment to kick in.
  • It didn’t.
  • I may be a simple ancient Greek mathematician from Alexandria but a game is supposed to, ya know, game.
  • Hyperbolica might just be a wee advanced for my simple brain-meats because I don’t get it.
  • I’ll stick with my smooth brain puzzle games like Superliminal.



  • Launches OOTB
  • Holds 60@UHD on “maximum”, although there isn’t really a lot going on
  • I swear every quirky physics indie game uses this exact same soundtrack
  • Controls are wasd


  • The hyper sonic lion tamer gives me a headache
  • I’m able to power through it eventually, but damn, it hurts my brain
  • After wandering through a city for a while, I talked to an oracle who told me to find a farm
  • I was then tasked with exterminating gophers. Which, to it’s credit, the game does give you the strategy. Unfortunately, it’s find a beeg gopher and fire until it decides to show it’s noggin again
  • Rinse repeat 10 times
  • I do appreciate the effort to do something innovative. The three maps and how they combine to orient your euclidian brain was interesting
  • But oh god my brain. It physically hurts.



  • Launches out of the box
  • On the Steam Deck it holds 60FPS on the maximum preset at 1280×800
  • Controller bindings are sensible and they work out of the box.
  • Can’t really complain about the controller inputs but I can about the keyboard ones.
  • On this box I tried playing it with mouse and keyboard to record the video.
  • It’s WASD only (the directional arrows do nothing) and you can’t rebind the controls.
  • Minus one chair right off the bat.
  • The graphics are pretty simple and there’s not really any voice acting involved.


  • Meh.
  • As a videogame, it’s pretty mediocre.
  • It’s a bunch of fetch quests to make way for the overarching fetch quest.
  • As a tech demo and proof of concept, it’s alright.
  • Some of the puzzles actually do actually require you to make use of the hyperbolic, non-euclidean physics.
  • But the thing that stuck out to me was how whenever I started moving my character in game, either on the Deck or on this box, my upper torso leaned back by itself to try and compensate.
  • Kudos! Your video game directly impacted me in the real world.
  • Unfortunately, the impact was just vertigo.
  • I would give it two chairs but not allowing people to rebind controls in 2022 is beyond inexcusable.
