Question / Help Sudden FPS drop

[kirmora]

When I stream League of Legends, or any other game really, everything runs fine for X amount of time, then suddenly I get a 90% or so decrease in my FPS which usually lasts 10-20 seconds. Why is this?

personally i dont really see anything thatd cause that kindof issue...that is, other than the fact im seeing youre using window capture and monitor capture at the same time, which could cause high cpu usage. Maybe someone else with more experience can weigh in and help u solve this issue.

 

[kirmora]

at one point, i switched added a game capture scene while i was using a monitor capture, this was only for like 5 seconds tho.

 

[bart2712]

oh ok...that video adapter, is that an onboard video card?

 

[kirmora]

I'm sorry, I am a little computerly challenged, what do you mean by "onboard"?

 

[bart2712]

i mean, is the video card your computer is using built into the motherboard?

 

[kirmora]

No, it is a Radeon 7950, connected to one of the PCIe slots on my motherboard.
