Zwift has been freezing the last two nights

I will be riding along and the screen will freeze.  I don’t lose internet connection because all the other riders are still there.  My person freezes for 10-30 seconds and the timer on Zwift will only go down 1-2 seconds.  Both nights I was able to get through my workout without losing data or crashing.  I watched the resources on my computer.  The memory was very stable at about 40%, CPU was very low <10%, Network was very low (I am using hardwire) but my Disk seemed to be the problem.  At certain times it would go to 100% and then Zwift would lock up.  I had no other programs running tonight.  My hard drive has 900 GB free. 

This is a new problem for me since the latest update.  I love the program and want to help you figure this out.  I noticed that some other people had similar issues on a Mac but I am on a PC.

I had Zwift lock-up and eventually crash on 01/03 and 01/04 as well.  Both times were within a few minutes of me completing my rides :-/  

Hopefully you’ve entered a trouble ticket to Zwift with your log files so they can determine what’s going on.

Mike, I’ve created a ticket from this request so we can investigate further. If anyone else is experiencing this, please submit a ticket as well. Thanks! bit.ly/zwiftsupport

I’ve had Zwift freeze up and the program becomes unresponsive in the past week.  This is first time that I’ve had any sort of issue or problem.

5

In my experience, when things like this happen it is usually due to overheating on the GPU itself. What PC/laptop/GPU are you using to run Zwift? 

Is it just Zwift that locks up? Or the entire computer itself? 

6

I have a Dell Desktop with Intel graphics. I have not had a problem until the recent update. I have also found that if I ride easy there is no problem.  Only Zwift pauses. 

7

I have a Lenovo laptop with an Intel 4600 graphics card.  Zwift is the only program that freezes; Trainerroad will continue to run as normal.  There also doesn’t seem to be any heat issues when this happens.

8

This happens to me too on my Dell Inspiron 17 core i7

no heat issues

ditto trainer road fine although I usually run this on iphone and keep pc for just zwift

 

Have entered on separate ticket

Having exactly the same issue on my Mac running Mavericks. 

10

For me Zwift is freezing after 25 minutes (mostly when I approach a hill).  I have to turn everything off to start again.  I also am getting no power ups or close the gap messages. Please help

same here.  I have a fast internet connection, have an internet signal booster on top of that, have a usb cable, do not have any thing causing interference, have tried a wire connection, etc, etc, and over the last week or so, i get freeze ups and slow streaming.  Last night when I logged in, the program was running slow from the start.  I rebooted the computer, reset ANT, tried  a wire connection vs wireless, nothing worked.  Noted there was an update from Zwift.  Very frustrating.  Do you need to be a systems analysis to make this work correctly???

Same issue here the last couple of nights. So frustrating especially during workout mode. I had to give up tonight. Unusable. 

I note that during workout mode it would freeze & when it resumed it would continue where it left off which makes it really hard. One of my efforts was +1 minute of extra time.

13

Yep having freeze issues in past week or so. Zwift will hang for 30 secs up to 25 mins. MBP Mavericks + Neo. No changes to setup.

14

Same issue here. Late 2011 Macbook Pro, 10.11.3.

15

I just had freezing on Zwift for the first time – twice in 1 hour of riding. This had never happened before.

 

I’m on a new Macbook 12, running the latest version of el capitan.

16

The last few days I have the freezing as wel.

I drive a Tacx Neo with a Tacx Ant+ receiver.

It freezes about 20 to 30 times in a 60 minute ride.

17

Locking up for me tonight.  Multiple times within first 10minutes of ride.  Rebooted computer (macbook air), router, kickr, no win.  Gave up.

18

Same issue: brand spankin’ new Toshiba Core i7 laptop w/ 4K video running Windows 10 Enterprise with no bloatware, and hard lockups every few minutes, lasting anywhere from 5 to 90 seconds.

19

Yesterday an update and the freezing seems to be worse.

The first minute 3 freezes.

PC is way above the minimum needs for Zwift. Network is more then fast enough.

Better log a ticket

I solved my issue - I didn’t have enough upload bandwidth, another process was chewing it up simultaneously. When I stopped that Zwift stopped freezing/stuttering.
