I just tried to play this now, freshly installed, and Im getting double vision, a bit like looking at SBS on my desktop.
Ive tried restarting, resetting profile (not sure why since I hadnt altered anything), attemption to change the resolution – which very hard to see at all because it has some very low res set and is tiny being double vision!
Better not to dismiss any of these messages, the restart hints also aren’t just shown for fun. They are shown whenever vorpX makes changes to game config files. In most cases such changes aren’t applied immediately since games aren’t really aware of them until they reload the config file in question. Hence the restart notifications.
