View Full Version : Connection / Update Speed since 5.x update

I couldnt use the VTT from the Launcher -store- Update till now.

1. Since one of the 5.x updates, my connection to Lobby in Win11 waits too much to get online. Therefore,
2. The Launcher stalls for some seconds to Update --if I directly press Update as I open the Launcher, it says "we detected another instance" but this is the only instance.
3. Also, Update speed is visibly slower. This didn't impact me except for a full reinstall after formatting Win11 but still it is visible.

Note: I've given the exe all the permissions --and it is in the Firewall/Antivirus exceptions.

What should I do?

It sounds partially similar to an issue I have, particularly the fact that if you click Update without waiting for a bit first, the updater will tell you that FGU is running and needs to be closed.

I never found the real cause, but I found a correlation between the issue and using a monitor with G-Sync. Here is the workaround I found to work for me:

It's worth a try to see if it works for you too.

This only happened to me after one of the 5.x updates.
I tried 60 Hz [down from 165 Hz] but it didn't solve the issue the first time, probably because my monitor doesnt have G-Sync.
Next time I tried [after closing and reopening the Launcher] it worked.

Thanks for the solution.
