Question / Help Fps on Obs go from 60fps to 30fps or less games stays normal

[Fabian.]

Its weird the fps on obs go down to 40, 30 or sometimes less, accordingly obs says that its not dropping frames. I stream with a wifi adapter (always have) and never had this problem, I was streaming with streamlabs obs and had the same problem, I switched to OBS studio and seem to be working perfectly last night, I start streaming again today and it happened again, I don't know what to do. Also I have an extra gtx 970 lying around, I had it on my pc but I know sli doesnt work really well with streaming so I took it off, would I get better performance in games while streaming if I put it back on (with sli off) and use the second card as the encoder and primary card for gaming? if so how would I set it up

thank you in advance and sorry for bad grammar

Log schows ~5% dropped/lagged frames due to GPU overload. Maybe try again with fps limit ingame to keep some spare GPU power for OBS.

I think I found the problem, Nvidia control panel was forcing anti-aliasing and some other settings, I switched it back to default and seems to be working perfectly now. Now I just gotta wait if somebody knows if putting in my other graphic card would improve performance or not.

Usually adding a second GPU for NVENC does not help at all (if your mainboard will reduce PCI-E lanes from x16 to x8 it will only get worse).
The reason for that is, that the encoding via NVENC does not add a lot of additional load. What does increase GPU load is the rendering and filtering of the scene, which can only be done by the same GPU that is running the game.

Ok thanks for the answer I guess Ill stick to 1 gpu, also I brought down the bitrate from 6000 to 5400 and now I dont have dropped FPS at all and the fps count stays on 60.
