Bug Report FPS immediately drops

Hi,

I recently tried out using OBS (right after the .452A update dropped) and am having some issues with framerate.

When starting up the stream in preview using gamesource, the fps is as I set it in the options, generally 30. as soon as I start to move my character around within a game the fps drops drastically to ~15

I tried alot of different settings, more than in the attached log, but all of the had the same problem even the lowest possible setting I could make 640x380//0 quality//30 fps//ultra fast x264 etc. But when lowering the resolutions the fps dropped to higher numbers ie. if I ran it at 60 fps with 640x380 the fps when moving would drop to ~40.

Here is some of the logs:

i'm pretty newb at broadcasting, but I've used x split successfully at 30fps and 720p without much issue so I was pretty surprised when 380 didn't really work.

any-who hope i can fix this because I'm really liking the program!

First thing that stands out to me is you have your preset at medium. You should leave that at veryfast

I did for that period of testing, I changed it back and forth alot from medium to veryfast in that log you can see the 380 resolution test was set to veryfast and it still did the same thing

you are getting an unusual number of lagged frames, and this is really unusual especially for game capture because game capture isn't really supposed to be using any CPU, nor should it cause any frame lag, nor should it even affect your game at all.

are you running any other game capturing software, such as fraps, or any sort of overlay software, or anything like that at all?

nope, even to be sure I did a clean boot at one point and just opened up the game and obs but it still happened. :(

*Edit*
I just realized that you may be misunderstanding whats happening a little Jim, probably due to my incoherent babblings heh 1am forgive me.

anyway,

the game itself does not lag or lose fps, Im taking the fps on OBS itself when it is broadcasting (the little readout at the bottom right of the window) its steady when in game I am not moving but when I start to walk around the fps on the readout drops drastically and it becomes noticeable in the broadcast. ie from 30 to ~ 10 - 15 even at incredibly low resolutions that my rig should be able to handle.

What game are you capturing? Also, do you have any other sources in your scene?

at first i had my webcam hooked up but i took it off when things were not working too well, other than that no other sources are hooked up. also I am capturing torchlight 2.

I'm not entirely sure what could be causing it at the moment.. If you find out what specifically is the cause, let me know. Maybe drop by chat some time as well

I think I figured it out:

I started fiddling with the in-game settings and it dawned on me that maybe this program i use called windowed borderless gaming was screwing it up somehow (it forces all windowed games to run without those pesky borders!) so I proceeded to test the game with it off.

I ran it in all the modes that TL2 supported and it appears as though it doesn't receive a fps loss when it is in windowed mode WITH borders. Fullscreen and windowed fullscreen as set in the torchlight menu both caused the fps to grind to a halt at 9 FPS, the strange thing is that this was constant from the moment i started the game up. With the program I was using (windowed borderless gaming) the stream ran fine when I was not interacting with the screen.

heres a log of 1) fullscreen 2) windowed with borders 3) windowed fullscreen:

it worked smooth as butter in windowed mode, its just a shame i have to have those ugly borders =/ but oh well! at least it works now.

I am having the exact same issue, as soon as I try to stream something in fullscreen or borderless windowed mode, I drop to 6-12 fps, from a constant 30 in windowed mode. The first stream in the log is in fullscreen, the second in windowed mode until the last 5 seconds or so where I switch back to fullscreen.

According to the logs, it's spending all your time trying to copy the data from the GPU.. this could be a graphics card related issue. The app renders everything on the GPU for image processing and conversions, and then copies it off the GPU when complete. I'm not sure about the specs of those video cards though.

To find out, try turning down your resolution/FPS and seeing how that affects the result. If it does, then it's probably the GPU causing the slowdown. Not entirely sure though

I tried changing both my desktop and in-game resolution as you suggested, I still hovered around 10 fps, with the occasional spike towards 15 or so.

Are you using a second monitor to check the fps? I have a similar behaviour in Rift when i tab to desktop the game throttles down pretty much to about 10-15 fps too. Maybe TL does the same thing when it's not the app in the foreground!
Do you expirience any lag when you actually play? or just when you check your fps in obs while tabbing out of the Game?

Yes, I keep the OBS window on a separate monitor to the game, the fps goes back to 30 if I tab out of the game. The fps drop is during gameplay and most menus (I go up to 20 fps in the menu of "Of Orcs and Men")

I get the exact same problem, the fps drops when i focus on the window of the game, when I de-focus the fps returns to normal (whatever I set it at in obs)

I recently tried disabling my second monitor as well as SLI but the same thing still happened. When the window focus is on anything but the game the capture looks smooth as butter unless its in bordered window mode (in this case even if I am focused on the game or another window it remains smooth) really cant think of anything else to try to fix it :(

Interesting, maybe drop by chat if you have time when Jim is around and try to live debug it with him.
He's normally awesomely helpful.
