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. ---

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?  ---

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.  ---

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. ---

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. ---

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. [Next page](https://forums.zwift.com/t/zwift-has-been-freezing-the-last-two-nights/8202.md?page=2)
