Can someone explain why Zwift is slooooooooooow?

It’s a snail of a program!

Booting it up takes forever!
Getting a ride going takes forever!
Quitting out of it takes forever!!

Tried My Whoosh the other day and it’s so much faster.

Never in my 40 years of using computers have I encountered a piece of software that was so sluggish to do anything.

Can you describe what you are running it on? What’s the hardware?

Buy a decent and properly configured computer in a store with proper advice.

I use Zwift on a 12 year old Thinkpad W520, don’t find it unusually slow.

Interesting first engagement on this forum.

We have no idea if the hardware is adequate or not. I’d love to see the details so we can understand if poor performance is expected or not, and exactly what is meant by slow. If the hardware is good and slow really means slow, that would be an interesting thing to dig into.

I use it on my iPad, 9th gen 5 years old, and mirror it to an LG 32 in tv. It works slicker than an oiled up slick thing. I don’t think the app is the problem.

Rubbish. Poor programming is what it is.

Core i7 3 GHZ
8 GB Ram
GeForce GTX 1070

It most certainly is not my PC, and why would it be when it’s not doing anything taxing???

What type of hard drive do you have?

Samsung something or other.

Sounds adequate. Which generation is the CPU? What did you get from zwiftalizer? Curious about the frame rates and load time you are seeing.

When you look at CPU utilization, you need to focus on the single most busy core. Most of the CPU will be unused and performance will be limited by whichever core the game is camped out on.

I don’t know tbh. I did buy the system a long time ago, and it was sold as a gaming PC. But I fail to see where CPU utilisation comes into it, when what we’re talking about is loading times, and the game itself runs fun…once it decides to actually do what I’ve asked,

There are two primary types of hard drives: Solid State Drives (SSDs) and Hard Disk Drives (HDDs). HDDs, like SATA drives, are traditional storage devices with moving parts. SSDs, such as NVMe drives, are newer and faster, using flash memory instead of spinning platters.

If you have an HDD, that is likely the source of slow load times.

With the performance analysis, which would also tell you the CPU model, that would give us the information needed to compare what you are getting to what other people are seeing with same or similar hardware.

I’m also still unsure whether what you are seeing and perceiving as poor performance is actually normal (ie, you have expectations that aren’t met and you’re entitled to that opinion) or if there is really some kind of problem and what you are seeing is not normal for people with similar equipment, in which case it’s a solvable problem.

I already know that. I have two hard drives, one is a SSD, but that is for the OS mainly.

Zwift has to be on SSD or it will suck.

It’s not “normal” on my planet, it’s completely abnormal. The truth is it’s bad programming.

As opposed to the thousands of other programmes there have been over the years?

Venting about that is a waste of time you could spend riding your bike. The game has big assets to load. Don’t run it on mechanical storage, or pick another game that meets your expectations for loading from slow storage.
