ScummVM Core Hanging

Libretro Cores
#1

Having a strange problem with ScummVM. I can load up games no problem, but when I click on the screen (with the mouse or joypad) it will usually hang for a second or two and then return to full speed.

Using a nightly build, but tried the stable release as well and it doesn’t seem to help. Also tried turning off shaders, but same problem. Not having hanging/stuttering issues in any other cores either.

Also just wanted to say how much I love retroarch! Still can’t believe how amazing it is, but it just keeps getting better :slight_smile:

Can you run from a command line with --menu --verbose and see if it prints anything useful to the console when that happens? Errors, perhaps?

#3

Thanks for the reply. I will try when I get home this evening

Sorry for the late reply. I had trouble with the command line to be honest…think I figured it out.

I noticed this error:

[GL]: VSync => on [WGL]: wglSwapInterval(1) [WGL]: wglSwapInterval() failed.

#5

does it print that every time it hangs?

#6

Nope - no errors while the hanging occurs.

Thanks for trying to help me with this.

What about your computer’s CPU? is it jumping up to 100% when it hangs? And in RetroArch, if you turn on the fps counter, does it drop on the hangs or is it emulating full speed (as far as the frontend is concerned).

#8

The FPS counter stops on the hangs and the FPS drops to zero, then jumps back up to 60.

Checked my CPU usage and it always stays between about 5% and 15%. Also, it doesn’t jump up to 15% when it happens (just hovers within that range).

#9

Anybody having any luck with Scummvm? Still getting hanging all the time here.

#10

I could also never get any game actually to work under this core, unfortunately.

#11

Well, at least I know it isn’t just me… Are you experiencing the exact same problem or something different?

Thanks for the reply by the way.

I am having the exact same issue. On some games it’s worse then others. Like “The Dig” it is barley noticeable and plays great, but on Leisure Suit Larry 5 It’s so bad I cant play it. It just keeps hanging for seconds at a time. Beneath a Steel Sky is kind of in the middle. It hangs every min or so.

All of these games run fine in the stand alone scummVM version. So it might be the core.

I also noticed it might just be what i am testing, but it seems sierra games perform the worst and have the most freezing. As the lucas arts stuff seems to work fine.

Lucas Arts (Full throttle, The Dig) Seems perfect. The core is wonderful with these games. Sierra (Kings Quest 5, Larry 5) Un playable with constant hanging.

I also tested the above sierra games with the dosbox core and they run fine there. So It might be a scummvm core issue.
