Hi guys
I set Dosbox with
fulldouble=false

I noticed a slight but annoying flickering when moving from right to left...
Why?Does that happen to you?my monitor has a fresh rate of 60 hz
I wanted to report it to the staff

It could be a whole bunch of things, but bear in mind that a lot of games output at more than 60Hz so juddering is only natural.

Hi Silanda
I know but if I use Scummvm Emulator there's no flickering...Why?

ScummVM isn't an emulator.

Post your DOSBox config.
List the games you are playing
List the DOSBox version used

60 hz is under some of the resolutions set by DOSBox.
maybe try frameskip=1 although not sure if it will help for all outputs

DOSBox 0.74-3 or an SVN build of DOSBox that has no additional patches applied.
DOSBox-ECE is a fine build but due to various patches it has applied it is prudent to know whether the issue exists in plain DOSBox or was introduced with the -ECE patches. Sorry, should have been clearer.

I tried with a normal version of DOSBox v 0.74-3 but always occurs the same problem:f licekering Screen
If I buy a new monitor, with a higher refresh rate, the picture of DOS old games, will be smoother without flickering?
