Question / Help In-game PUBG FPS performance suffers over time - OBS?

[bbenton300]

Hi all -

I've browsed the web and various posts here, just looking to make sense of what I *think* is my problem.

Basic PC Specs:
i7 6700 3.4 GHz
EVGA GTX 1080 ti
16 GB Ram
Corsair CX750M

My issue - I want to start streaming, mainly to make clips, communicate with my group of friends, etc. I ordered the 1080 ti and a new PSU and installed them. Prior to the upgrades, I was running a GTX 960. I had solid performance, with and without streaming, but wanted it to improve. After install, I see a HUGE jump in FPS in-game (woot!), but after streaming/recording for a period of time, everything just bogs down and I can't quite figure out why.

What I'm doing with OBS: streaming straight to twitch and recording locally on my HDD (easier to edit and clip, IMO). At first, since it was always 1-2 hours into play when my FPS would drop from 80-90 to 5-30, I thought it was a heat issue. I downloaded a hardware monitor to track temps and usages, but nothing gets over 70 C for more than a short period of time, well within operating ranges.

After research, it sounds to me like OBS recording is likely very CPU-heavy and even though I'm not seeing usage spikes, over-time it's just not able to keep up? FYI, the game in question is PUBG - also fairly CPU heavy at the moment.

Just looking for some advice from anyone who is more tech-savvy than I, or some confirmation that I'm on the right track!

Thanks

PUBG still has horrible memoryleak issues. Restarting the game every 2 Games is probably your only solution. Also Streaming + Recording simultaneously can quite the load on your system. Balance the load by recording through NVENC and stream with x264.


Multiple people have the same issue. running the game with solid 80FPS and after a couple of runs it drops down to an absurd amount of fps sometimes below 20. Restart fixes it for a couple of games.

Appreciate the input - so far, it seems to be the combination of OBS + PUBG, as PUBG on its own is fine for hours. Restarting just the game and/or OBS doesn't always have immediate affects, but a full PC reboot works every time. Will probably have to just reset everything for now until they fix the issues!
