Thanks Lee, that worked great although my saves have gone but at least its playable. As for a bug ticket I don't honestly think this is something a bug ticket can fix and I'm not the only one with serious lag issues. I know the first release was 'early' but we knew that and took it on board but since then the QA seems to be notably absent from releases which is a real shame.

I don't have STEAM. I purchased the game DRM Free from Kickstarter, then humble, then transferred to GOG. Regardless, I don't want GOG to have anything to do with it because that's what upgraded it anyway without asking. 


So, for clarity, I want to downgrade to the version before the one that GOG downloaded and upgraded which from memory was 1.6. The new version is virtually unplayable, lags badly and creates instead of moving seem to appear and disappear and imps keep appearing in lava and dying. Hopeless to play.
