Question / Help Recording on Win7 PC tower - black screen

[Deleted member 56990]

I've been using OBS classic (current version 0.657b) for quite awhile now and have learned how to
adjust it for my current PC tower build and haven't had many issues outside of general slowdown because
of using it with my NES emulator (FCEUX 2.2.2)

HOWEVER, I have been experiencing two issues that, after reading through these forums, haven't found
an answer that I was looking for so I joined to post these issues.

1.) I am having issues with DosBOX games. I have the settings I use for FCEUX (Inner Window capture, 15 FPS,
and no capture mouse pointer) and have as much software not runniing as possible (to give more RAM and processor
time to my games and OBS). But the screen in OBS either comes up blank, or it shows the white startup screen in
the box that is set for the game window I am running.

Not sure what I'm doing wrong as the DosBOX uses up less resources than my FCEUX unless it is something in
the OBS i'm not aware of.

Help appreciated (log will be added as a reply)

you only have a single core. OBS and whatever software/game you are using to capture will need use of that core as well.


most people who encode have a minimum of 4 cores or more. I, myself use a 6 core, 12 thread CPU..

Secondly, your dedicated GPU is an old onboard nforce GPU. OBS will attempt to use the GPU to accelerate capture.

All I'm getting at is your PC is not fast enough to use OBS in an efficient manner. sorry man.
