Zwift is CPU limited in almost all contexts.
Yes but that doesn’t necessarily equate to a negative experience like the OP is experiencing.
There is definitely a performance difference with and without video screenshots.
I suspect that with it enabled it’s dropping performance below the point that the system can cope.
Thank you very much for sharing! We’re watching performance metrics and reports like this really closely during the initial rollout, and we’re going to continue tweaking which devices are included and excluded from the feature.
Was there any discussion about rolling it out to specific generations of cpu? You have a 12 year old cpu from the above user getting a feature that’s going to cripple performance when enabled
Can you give a reason that the i3 has been excluded from initial tests for users?
Hi @Rich - I assure you that the initial rollout is just a starting point. We are absolutely planning to roll this feature out to as many devices as possible, and we’re actively looking at i3s as well as many other devices (and conversely, we not want to cripple any devices, so some devices will be excluded as we get more performance data).
But as you know, an older gen cpu, especially anything that’s 12 years old is going to perform worse, this is my gripe about it being i5 upwards, the generation of the cpu doesn’t seem to be taken into account is all
Agreed. We’re definitely considering CPU generations within these buckets and the inclusion list will become more refined over time.
That’s good to know that the gen of the cpu is being considered as that gen 2 cpu is 4 core 4 thread but I’m guessing that it might come down to HD speeds
Are you running a mechanical drive or ssd?

Mechanical hd, not SSD.
This means you get a massive performance penalty that could be resolved with a $20 SSD and a windows install. Your old PC could have a lot more life with an SSD upgrade.

Hi folks!
Now that we’ve collected additional performance metrics on Video Screenshots for Windows over the past two days, we’re making some refinements to the rollout criteria which will increase availability of this feature for some device groups, and remove the feature for other device groups. I’ll also be more specific about the percentage of devices that this feature is available to, and will keep sharing updates as this increases over time.
Video Screenshots for Windows is now available for 10% of devices that meet the following criteria:
- Intel Core i5 (9th Generation and newer)
- Intel Core i7 (9th Generation and newer)
- Intel Core i9 (9th Generation and newer)
- AMD Ryzen 5
- AMD Ryzen 7
(How to look up which processor your computer has)
(How to determine Intel Core processor generation)
For Intel Core i5, i7, and i9 devices older than 9th Generation that are no longer included in this initial rollout, we’re continuing to review performance data and make improvements, and we’ll try our best to make this feature available for as many devices as possible so long as they can support it at a reasonable degree of performance. I’ll continue providing updates in this thread as we add additional devices to the rollout.
We’re also running pilots with smaller percentages of other devices, including Intel Core i3s and pre-9th Generation Intel Core i5/i7/i9s, and I’ll share more on those as we start to dial them up in the near future.
For devices that are supported, we’ll continue to increase the percentage of included devices over the next week.
Also, some folks on supported devices who had the feature available earlier this week may notice that it is no longer available - unfortunately, as we made some changes to the rollout distribution today, we unintentionally re-randomized the distribution which may have caused some individuals to be temporarily removed from the first wave of the rollout. If that was the case, your device is still eligible for the feature and will be included as we continue to dial it up over the next week.
Thanks for the feedback thus far!

probably why you had a performance hit then, the drive wasnt able to write and read fast enough
can also find the processor in the log.txt file and also the computerspecs.txt file in the zwift folder under my documents which is probably easier to find
been waiting for this for ages and have a I7 6700k that ive had built for 7 years or so thats done me so well for zwift, not sure if its worth moving to my apple 4k box for the screenshot feature as It looks so good!

Hi everybody,
I’m back with another update on the rollout of Video Screenshots for Windows.
Starting today, Video Screenshots is now available for 25% of the following devices:
- Intel Core i5 (9th Generation and newer)
- Intel Core i7 (9th Generation and newer)
- Intel Core i9 (9th Generation and newer)
- AMD Ryzen 5
- AMD Ryzen 7
Additionally, we’re enabling Video Screenshots for some additional device types not included in the initial rollout last week, also now at 25% availability:
- Intel Core i3 (10th Generation and newer)
- AMD Ryzen 9
We’ll continue to dial up availability of this feature over the next week, and are continuing to evaluate performance metrics for other devices for future inclusion.
Thanks for all the feedback thus far!

Hi @evan-zwift
Just wanted to give a bit of feedback… (from an i3 12th gen user)…
My system was put in the initial pilot (had this feature for 1 week) - so assume you can already see performance data - but from my user experience, the system is handling this feature with no issues at all, silky smooth! Specs below
I need to drop some rides into Zwiftalizer to look at exact FPS impacts but on screen there is no visible lag or stutter.
Saving of the clips (on Save Ride screen) is fast and had no issues.
I can see how older generation CPU’s would struggle to handle this - and I have seen some very ‘choppy’ recordings on Strava - so I would recommend turning this feature off if you notice any issues, especially when going through banners etc.
Thank you for the feature!
Specs: i3 12100F | 16gb RAM | RTX 3060 Ti XC 8GB | SSD

@Jon_Wakefield Thank you so much for the feedback and the specifics! This is incredibly helpful and these anecdotes are super useful in confirming what we’re seeing from the data.

I’ve got a i7-6700 Dell workstation with an NVMe SSD that I’ve been running specifically for Zwift and it’s been rock solid. Literally, since I built it, it has done nothing but Zwift. I’m interested to see how it works with the Video Screenshot functionality. I would be more than happy to serve as a Beta tester! Pick me! Pick me!
