Input lag GLK Lurking

Post by appoloin »

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.

Unfortunately, this may be something specific to just your system, whatever it is. I wasn't able to replicate any issue here locally on my Windows system.

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?

I don't know linux very well, but does it feature some kind of "mouse blanker" which erases/ blanks the mouse pointer after some idling?
If tes, you could try to shut that feature down just for testing.

I can't reproduce such behaviour either

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'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?

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 Firejail are Lutris wide defaults
there are no themes in DATA

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.
