This sound like a problem I encountered some time ago, I just switched to dosbox but this might help

This is just weird, I tried Lurking again launching it from Scummvm GUI and Lutris, when launched from Lutris the lag would happen but when launched from Scummvm GUI no lag.

OK, the workaround is obvious, use Lutris for the install and ScummVM GUI for the launching.

This is the command line Lutris using launch the game is anything wrong here gamemoderun firejail --noprofile --net=none /usr/games/scummvm --extrapath=~/Games/DATA --themepath=~/Games/DATA --no-fullscreen --gfx-mode=3x --path=/home/user/Games/the-island-of-dr-brain islandbrain Gamemoderun and Firej...

I've just finished Castle with aspect correction off, and the experience was a lot smoother. Now I wonder if my problems with Lurking where due the scaler option or the aspect correction, is that possible?

I not seeing an option like that in Cinnamon's perfs. I can add a bit more detail to the original post, I had two windows open, one was Lurking with no scaling, and the second was Trizbort.io. The Brain games where running fullscreen with scaling of 3X and aspect ratio correction (Lutris defaults).

I spotted some thing similar with BrainCastle and BrainIsland, a micro stutter if the pointer is ideal for too long, but I've just finished the Monkey Islands and there was no problem. I using Mint 20.0, Scummvm 2.2 it's the official built from here, launched via Lutris. Any ideas? ps Sorry the late...

It appears like scummvm goes to sleep, awakes with keyboard input but takes a second or two to catch up, once scummvm has caught up there is no lag.

Discworld Noir had problems long before we had multi cores.

Thanks. I forgot about the README, the wiki usually has the information I need.

What game files need to run Might and Magic: World of Xeen?

If you are on Linux there is an easy way. Lutris has an install script for the 7CD version, click on the unpublished installers (you will need an account to see) and click install.

Ok, the game does run in Wine so it still playable unlike some of the earlier Director games.

I opened REHM.exe (first game, english version) in GHex, there was one occurrence of "Macromedia Director" but nothing near by that looked like a version number. I did find a shockwave 8 entry.

Any tool suggestions?

Has anyone ever found a complete list of games released that use the Director engine. There's the ScummVM wiki list (https://wiki.scummvm.org/index.php?title=Director/Games) and a few more can be found on MobyGames list (https://www.mobygames.com/game-group/game-engine-director/). I can add Rhem 1-4...
