Shadowplay playback is choppy.

[Majestic]

So i'm trying to record some footage for a video i'm making. But there is this big issue I can't seem to solve. I'm trying to record some footage from Rise of the tomb raider (and the reboot "tomb raider). But every attempt the actual recorded footage is choppy. I render the game at 60 fps, but the recording seems to be variable (58-61 fps) and it doubles frames sometimes. It almost seems like the game engine and shadowplay are not synced, and shadowplay is just grabbing random frames. Eventhough the game was vsynced (triple buffered).

 

This essentially happens for every game I'm trying to record. I'm recording to my SSD at the moment, but streaming the data to my NAS doesn't change it (for better or worse). 

 

When I review the footage, and go frame by frame you can sometimes see it use frames a second time. Resulting in the choppy playback. Is there anything I can do to fix this, besides using a capture card? Is OBS with Quicksync any better? I don't really have the expendable system resources in some games to record from the CPU, since i'm only running a quadcore.

I havent had issues with OBS doing this...but I havent with shadowplay either. 

id give OBS a try though simply because shadowplays quality isnt steller.

1) How many Mb/s U set for recording ?
From my perpective, 1080 60FPS needs 50Mb/s (I use Big Kepler GPU).
2) What CPU/GPU U have ?

1) It's the high preset, higher than 50Mb/s isn't possible.

2) check my profile, it's all there. 

 

Even dropping settings, thus making sure locked 60fps, doesn't change anything. I can run the game perfectly, with overhead to spare...and it just duplicates frames.

Might as well try QuickSync + OBS real quick just to see if that works.

Where U keep temp files ?

Tempfiles write to SSD, files are stored in NAS. But setting tempfiles and stored files to seperate SSD's (phsysical) doesn't fix it.

Yeah, currently in livechat with Nvidia. Maybe they know something. After that, if it's not fixed, Ill try OBS.

Update: so i tried OBS with quicksync and this gives me the same issues. Random spots where the encoder and output aren't in sync or something and it just misses a frame. Resulting in a duplicate grab from the output buffer.

 

Just can't seem to get a smooth 60 fps recording without stutters. Is this simply not possible?

Soooooooooooooooooo, after lots of browsing I came acros this post:

Mr. LyrickCZE I thank thee. Cannot detect any more spikes after setting nvspcaps64.exe to high and the game to "higher than normal" (just below it).

 

Problem solved, but thought i'd update for completion if anyone found it through google.
