Computer for Zwift
I've been running Zwift on a very old desktop. It finally decided to join the great electronic scrap heap in the sky.
For those running Zwift on a desktop, what computer are you using? I asked a computer "guru" at a box store about what I would need, and brought in the requirements according to Zwift. He recommended a gaming computer for $1400. Uh, no. There has to be something less expensive that will be adequate. I'm not going to be running any games that require mega speed or graphics (I don't think - I'm illiterate when it comes to computer hardware.)
Suggestions?

Zwift insider just had an article about this: https://zwiftinsider.com/zwift-pc-guide/
The author, Dave Higgins, is the admin of a facebook group. He has written many guides about using zwift on a pc. They are included in the files section on that FB group https://www.facebook.com/groups/zpcmr
*read to the end of the user agreement before you answer the question.
The simple answer is that an old i3 running Win 10 will work. I think I have an i5. I don't think a $1400 gaming computer will get you much improvement. Zwift just doesn't use it.

IIRC, Zwift doesn't need a lot of CPU, but it benefits from a really good graphics card, if you want detail, frame rate, shadows, etc.

don't try this at home.
A new computer with an SSD drive will be great for all your PC tasks. People adapt to slow startups, lags, and other delays. Everything is snappy on new PCs.
I already had a gaming PC from a few years ago, via microcenter.com. It was the cheapest way to get a reasonably fast CPU and a good graphics card, and an "NVMe" 1 TB drive -- this has a much faster transfer speed than the usual SATA drives.
I got it for photo (and video) editing. Both the fast CPU and the graphics processing make edit changes instant, and video editing reasonable instead of tediously slow.
I have a 4K 27 inch monitor -- these are great for any PC task -- reading articles, watching videos, etc. Very sharp.
My PC: Intel Core i7-10700K @ 3.80 GHz (the PC boosts it to 4.6 GHz when needed) ; 32GB memory (but 16 GB is likely fine) ; GPU Nvidia GeForce RTX 2070 Super. I think it was about $1300.
A current "lower end" gaming computer: $850 AMD Ryzen 5 3. 16GB memory NVidia RTX 3060 ; 1TB NVMe SSD --- reasonably close to my setup.
https://www.microcenter.com/product/...gaming-pc?ob=1
What I like with my PC:
It's usually an instant launch when I click an icon. A few apps take 5-10 seconds to launch. those would have been 30,45, 60 seconds on my old laptop.
The big 4K monitor is so nice.
Even rebooting or software updates are very fast: 35 seconds to shutdown+reboot and ready to use again.
Copying files is so fast: around 300MB/second for big file copies.
I didn't know much I'd appreciate all these speed improvements -- I really like them.
I don't do games.
Just now, running Zwift with the Windows Task Manager to check on usage:
With Zwift, versus normal web browsing usage:
CPU: 25% vs 1%-5% typical
CPU speed: 4.5 GHz vs 1.1 Ghz -- it slows the speed when it's not busy, and the fans slow to a crawl. I hear them spin up for short periods when I do something calculation intensive.
Memory: 13GB vs 10GB So around 3GB for Zwift, not bad.
GPU video card: 25%-33% in the "3D" portion, low usage in the rest of the video processing; vs 2%-3% for web browsing.
I'm running Zwift in 4K mode: the graphics look sharp, and it's calculating shadows and other effects in the scene. Are these necessary? I like the interesting scenery design!
Would it be okay at 1080p or 720p? I switched the mode to 1080p and it's not bad. Some more fuzzy edges on objects, etc. Some of the cool effects might be missing. But the info boxes are just as readable, and I expect the game play isn't any different. Woulld a slower frame rate be annoying? Not sure.
I like solo sessions on Zwift, doing free rides or planned workouts. I have time to look around the scenery, etc. In fast group rides or racing events, all my concentration is on rider positions nearby and the stats in the data boxes. So a lower resolution display would be okay for these competitive events, I think. Is there any lag or other problems if the computer is slower? I don't expect much of that.

Zwift insider specs:
The CPU and graphics look fine.
He says 8 GB of memory is okay, and it probably is. if 16 GB is just slightly more expensive, I'd get it.
He says 128GB SSD is "easily enough" --- no. 1TB NVMe. Maybe 512GB if you don't have lots of video files or other large usage.

i think if you spend more than $500 you will hav eenough compute power. i am using a crappy laptop that does have a SSD, my previous crappy laptop had a HDD and althogh painfully slow to start it worked fine once it was running. current machine when i last used it was better at the startup but no different in acutal use. i was casting it to a large TV.
i dreaded the updates, glad to hear they figured out how to defer updates until after a ride. that always irritated me.

I recently bought a refurbed PC on EBay for $200 with specs that followed the guidelines from Dave Higgins FB referenced above. It’s running Zwift in Ultra mode just fine. You don’t need a high end gaming PC.

I guess I should add that this computer will be for Zwift only. I have my "main" computer in a room in the house that is separate from the room I have my bike and trainer set up. So, I'm not really concerned about running other programs (I do my photo and video editing on the main computer, along with just about everything else including CAD)
What about getting a newer computer (possibly a refurb unit with SSD, sufficient memory, crappy video) and upgrading with a better video card?

I buy used computers from the local university and put an ssd in them. You can use a 250gb ssd if it's dedicated computer, which mine is, although I think I have a 500gb ssd in it. They sell you 250gb ssd for the price of shipping nowadays. I had an okay graphics card sitting around. It's not quite as good as the one that Dave Higgins recommends, but my computer is in a half-height case and doesn't have a very big power supply and I'm not too obsessed over graphics quality. I probably should have just left the card that was in there. I found out from experience that it's possible to get a card that zwift won't run on. I am using a 20" computer monitor sitting on the floor. Someday I'm going to hang it on a wall mount. Including the monitor, I probably have $150 invested in this computer.

im seeing a lot of cheap PCs on craigs list that would be adequate for zwift. might start there if only for zwift. pc/laptops generally have graphics built into the MB anyway. none that i have used for zwift have had a spearate card. maybe i have a low bar when it comes to graphic quality, zwift is a cartoon to me, but still fun.

What about getting an Apple TV instead? I don't have one -- using an old gaming laptop -- but I know lots of indoor cycling riders use the ATV and it tends to be well supported b/c there's no issues with driver compatibility and such.

+1 for Apple TV. Cheap, reliable and there is a native Zwift App for it. No need for an expensive gaming pc.

There's a Facebook group dedicated to collecting information about PC builds for Zwift. There's a lot of good information there. Basically, you need a newer generation Core I3, 8M ram, and preferably an SSD drive. A decent video card is also needed if you want to run max resolution and frame rates.

Well, I picked up a new Apple TV 4K with Wi-Fi and ethernet for $160.
Evidently, you need an Apple ID account to download Zwift. And evidently, Apple won't let me create one.
I'll be returning this POS tomorrow for a refund.

Why not just get the current version? But if you are looking at used ones, then I think any of the 4K versions should be fine and they have been around for years. I would imagine DCRainmaker has reviewed most of them with Zwift.

It was. After two days and many hours between chat with Apple support, which was escalated to a higher power, which became a phone call and then giving permission for that person to see my computer screen as I attempted yet again, it was finally resolved after much trial and error.
Of course, then the Apple TV said I had to log into my iTunes account before I could download Zwift. Why that is, I have no explanation for. I think Apple tries to force you into their Matrix somehow.
I had downloaded iTunes previously, and when I couldn't log in, I removed it with Control Panel. Tried to reinstall, and was told it couldn't be installed due to a file that was of a later, updated version. Several more hours researching that issue, found the folder that the file had been in - evidently Control Panel left that behind on the uninstall - and deleted the folder. BTW, the file wasn't in it. After a clean reinstallation and signing into my iTunes account, I was able to download Zwift, and all is well with the world.
Except I ran out of Prozac.

I just got a small form factor optiplex i5-6500 I paid $50 for and an rx6400 (I also have a gt 1030 I could use) and although the rx6400 gives me the basic profile, I can see shadows and stuff and get framerates in the 70s and it also streams at the same time. and i can always use it as a proper pc if I ever want to.

I inherited an iMac from my father when he passed last year. It's about 5-6 years old and runs Zwift without issue. 21" monitor, good sound, saves space. Working for me. It's one of the older intel-based Macs, and knowing my dad, probably the minimal specs.

UPDATE: I finally got things working - sort of. I will preface my next statement by saying that I hate everything Apple (sorry, Apple fans).
The circular touch pad thing on the Apple TV remote is SO DANG SENSITIVE that looking at it moves the selection on the screen. I hated that thing on the old iPods when they first came out (I admit, I had one, got rid of it after it repeatedly locked up on me.) With care, patience, and a few choice cuss words I can actually start the app, pair my sensors, choose my route, and start pedaling. However, when I'm done, I go through the care, patience, and cussing again to move the selection to the EXIT door on the app, and..... nothing. It refuses to accept the input.
I swear, I don't even think I'll drink apple juice anymore.
