I've noticed that sometimes a player drops out of a match due to connection issues, and when they rejoin, they do so as a spectator. It's not frequent, but I've seen it happen a couple of times. Also, when I use windowed mode, the game freezes when I minimize and then maximize it again. I hope this helps.

Anytime my friend, and absolutely, I will send a screenshot of it here. I do not have any mods enabled in the game, and yes, I will move the ones in the mod folder to a temporary folder for now.

Hey @willbont thanks for taking the time to test. Any chance you could upload your interestinglog.html ? See https://gitea.wildfiregames.com/0ad/0ad/wiki/GameDataPaths Do you have any mods enabled? Can you move all of them out of the mod folder temporarily? Just to rule out side effects.

It’s barely noticeable, so it doesn’t really feel like a big downside compared to the improvements.   IMHO, yes.

As far as I know, there isn't. I keep my settings at Medium (with shadows at Low) and there isn't any lag with R28, except in extreme late game with hundreds of units on the screen.
