Question / Help Game lag while running obs. specs seem ok

My situation is strange. While playing arma 3 and streaming I get roughly 50 fps in game. My ping is about 60. CPU usage about 30% memory usage about 20%. But the game runs like crap acting like there is lag even though specs and ping are fine. Shut OBS stream off and it smooths right out. It also does this on preview not just stream. Only thing that comes to mind is maybe OBS cashe is going to my primary hard drive? If this is what is happening where is the cashe/temp files going and how can I change the directory to my secondary drive.

The x264 encoder that OBS uses can be configured to use more CPU than the worst running game on the planet. You should post a log file so we can see some data on what's happening.

I am stuck at work right now so I can't get u a log file. I have tried just about everything. I turned game settings all the way down to low. At the same time I also turned obs way down to a 200 bit rate and the lowest possible res setting. It didn't not matter what the settings were. Obs still lagged the game even though my specs were very stable. A ping of 64 and fps around 50. Even higher when on the low settings. My system was not bogged down In the slightest or was my connection. I have seen this kind of lag before when I used shadow play and had it saving to my primary drive. No shadow play was not running during my trouble shooting. This is why I am asking where OBS saves it's temp files before it uploads them. If it does.

ok. Well again. ill post it in case it was missed. i only was using about 30%cpu, 20% memory 40-50 FPS and getting 60 ping. internet is 50 down and 5 up. in addition to that i lowered all game settings down to the lowest and IN OBS lowered both my bit rate and my resolution down to as low as they can go and got the same result. It also happen is preview mode not just stream. Unless someone can point out where i may be mistaken then this is not a hardware or a connection issue. My only weak point is probably my hard drive being only 5500 rpm. but if OBS doesn't write to the hard drive and stream directly to twitch then i shouldn't have an issue. Thx for the responses but i still have an issue. any more suggestions would be appreciated thx.

Have you tried using differnt capture methods? If you do a window capture with aero enabled does it perform the same?

Problem solved! Thank you flavored for your suggestion. I am not sure why but OBS and Arma 3 do not get along in windowed mode. i tried both full screen windowed (what i was using) and just windowed with no change. Then i just did normal full screen and ran nice and smooth. Also Aero was already on i didnt have to change anything with that. Thank you for your help. you can imagine how frustrating that was lol. Any way we can get that patched or fixed so OBS will work with windowed? makes things easier for tabbing to multitask while running twitch. thanks again. either way i am super happy we got this resolved.

They don't, where in the world you got that from?
Click to expand...

where i got that from? from 3 workstations i have an i5 i7 and an old i7 extreme the i7 get for whatever reason horrible ingame performance @ 1080p but arent even using that much of the cpu

if it would be only one of the workstations i would have ignored it but 3 + the same happened to a friend of mine

they are also running all on different boards ram hdd and gpu's the worst gpu i had was a 660ti so this shouldnt be a problem :/

@alpinlol Other than this issue i have had no problems with performance. Even in arma 3 which is really resource heavy. In full screen mode while streaming i was still getting 60 FPS.

I have also had no problems with my stream. But will see how it goes. If anything pops up I'll post about it. Only time I had stream issues was when I first started. My Internet upload was only 1 Mb up. Soon as I upgraded all stream and vid quality issues went away.

Ok problem not solved unfortunately. seems to be a problem with my dual monitor setup. Any time anything is running in second monitor like flash vid obs whatever doesn't matter what it is. It will lag both monitors. Reason is they are not running at the same resolution. unfortunatly my second monitor is a bit older and is not capable of 1920x1080. max res for second monitor is 1280x1024. If i drop primary down to that res it works perfect. but who the hell can play like that lol. Not this guy. if there is a work around anyone knows of short of buying a new secondary plz let me know.
