Is it possible to build a gaming system that could run Zwift with this? 4gb version is only $55!
Your kidding right. It doesnāt even come close to having enough graphics power for Zwift. It can run Minecraft though, lol.

Now you know how little I know about computers. Haha.

Add the cost of whatever version of Windows is available for Pi to the $55.
What are the lowest resolution & display settings Zwift will run?
A cut-down verison of Windows designed for the Raspberry Pi and other similar low-cost single board computers called Windows 10 for IoT devices is actually free, but the CPU on these devices are so slow it takes longer than forever to boot into the full Windows 10. Pi 4 is faster so it probably takes slightly less time than forever.

While I agree with the other commentators that the Pi4 probably doesnāt have enough graphics power to run Zwift, I think this would be a great platform if the folks at Zwift HQ wanted to build a basic turnkey system (based on Linux or Freebsd) that could run Zwift as an appliance.
Maybe Raspberry Pi 5?

Iām currently using a Pi3 B and SteamLink to stream zwift from my gaming computer to my little spare room gym. Some way down the line a Pi version of Zwift would be awesome.

if youāre looking for small and inexpensive, appletv is probably the better play:
we already know zwift works well there, and the 32gb version is $179.
even if the Pi could run it, itās going to take some jerry-rigging without a supported version.

Hi here. Sorry to bring up an old post, I was just wondering if this setup works well with sensors - that is to say I have an ant+ USB adapter. Does steam link forward the dongle info from the RPI to your main machine?
Iām pretty sure that steam link is basically an advanced remote desktop tool - so it really doesnāt have to forward anything more than the graphics and sound of the app - so it should work. Have not tried it though.
If anyoneās still reading this, Iāve got things up and running between two windows machines, but had to use a separate program called virtual here for ant+ forwarding. Itās an ok program which requires occasional tinkering but works well most of the time and is free if youāre just using 1 device. Thereās a Linux version too so should work fine on the RPI, thatās the next project.
In addition, the Zwift launcher doesnāt play nicely with steam, so I have to stream notepad, and then minimise it. Then I can just use it as remote desktop which works fine.
For what itās worth, it is actually possible to get Zwift running on the RPi4. Itās been a bit of a faff and been waiting for one of the supporting Android builds to include ARM64 support, but got it working today.
I wonāt lie, Iām overclocking it quite a bit (2GHz) and the UI is a bit sluggish (menuās), although the actual in-game animation isnāt too bad.
It found and paired with all my sensors (KICKR + TICKR + Wahoo Cadence), and also connected to Companion App on my Tablet.
Definitely a big step up from using my phone (couldnāt cast due to broken WiFi, so small screen only).
I donāt know how repeatable it is (in terms of getting it setup), as I went through a bunch of combinations before actually getting it to work and Iāve not tried to replicate it from start to finish. But itās definitely possible.
And anyone thinking the RPi had no chance on performance, was always way off I honestly thought it would probably come up short (though not by too much, itās a beefier setup than most people realise).

that is really cool! i thought the pi only supported an older version of open gl? maybe that is enough?
I believe the RPi 4 supports OpenGL ES 3.1, which is only just behind the curve (I think 3.2 is still latest).
Iāve got a workout planned this evening, so will put it through itās paces properly.
Iām also going to order a cheap case with some active cooling (+heatsinks) as I imagine that with the overclocking it might start to get a touch toasty

Iāve used it a couple of times now and looking pretty good. Iāve actually put a short article together on how to go about the installation.

I used your info to duplicate and it works just fine. I only overclocked to 1.8 and no problems during 30 minutes of riding. Picked up everything on BT (Snap, cadence, oh-1). Graphics not quite smooth but not badā¦ Didnāt distract from the ride and I normally use aptv. Better than what I started with - a old hp laptop. Graphics about the same but it took forever to fire up windows then zwift so the Rpi4 is superior.
Must be something on your end, because when i did this i ran zwift in 4k over lan-cable to my raspberry pi and the only issue i had was that the steam-link app got updates often.
It allways started zwift no problem, even with zwift-scripts to make it remember my login details so i didnāt have to go back and forth.
You can run android on raspberry hence you should be able to run zwift, but there are better alternatives out there like some of these:
If you absolutely want to go the DIY route, wich i encourage you to do as i also like tinkering with these things.
I will actually tro this myself now, with the older rpi3b because thatās all i have thatās not doing anything.
