Mouse lag in prboom+ & dsda doom

[Blaster9078]

So I've started getting into recording demos on doom and I really like it, but, in prboom+ and dsda doom I feel a bit of mouse lag even when v-sync is off. The lag is most definitely there because I don't feel it in crispy doom. I really want to use dsda doom for recording demos since it has more features for speedrunning and has wider compatibility with PWADS than crispy doom. If someone could help me minimize this lag I would greatly appreciate it. If there is no way I'll just use crispy doom since so far I've been only running the official IWADS.

Is it like input lag or more like it's choppy/jittery? If it's the latter, reducing your mouse polling rate to something like 125 may help (a lot of gaming mice software have this option in the profiles section). You might also wanna double check if "Enhance pointer precision" is disabled in the Windows' mouse settings as well.

It's like input lag. It's more noticable when quickly switching directions

I thought It was lag, because I used to play a lot in ZDOOM derivated ports.
But thats was not the case, movement is rather different.
Not sure if its the same thing with you.
If you played it before without issues then something is wrong.

Funky. What are your mouse settings in the cfg file? Mine look like this and it feels fine:

 

Spoiler

# Mouse settings
use_mouse                         1
mouse_sensitivity_horiz           18
mouse_sensitivity_vert            0

 

[...]

 

# Prboom-plus mouse settings
mouse_acceleration                0
mouse_sensitivity_mlook           18
mouse_doubleclick_as_use          1
mouse_carrytics                   1

 

[...]

 

movement_mouselook                0
movement_mousenovert              0
movement_maxviewpitch             90
movement_mousestrafedivisor       4
movement_mouseinvert              0

This is also something to consider. Mouse behavior feels very different between ports, even between forks like UMPAINFO and DSDA-DOOM. Crispy even has acceleration on by default for increased accuracy to DOS, which is absent by default from others (could this have something to do with your perceived lag in DSDA and UMAPINFO?). Personally I like the standard DSDA-DOOM and GZDoom inputs the best.

 

Edit: Firebert reported a similar issue in the UMAPINFO port thread. If all else fails, try running x32 with x86 dependencies (although it doesn't seem to be a definitive solution). Also, might wanna try running this with and without a launcher like PrLauncher or ZDL to see if it makes any difference.

Disable "mouse acceleration" on Windows.

Do you have the same problem in Woof and Eternity?
