    I think you mean NvENC, not CUDA. Yes I was using NvENC external plugin in Afterburner, but the performance impact was far greater than ShadowPlay, especially in CPU-heavy games (since it increases CPU usage while ShadowPlay does not) and in DX9/OGL games, which seem to have much less efficient/higher overhead capture than DX11 games. Like PlanetSide 2 is literally unplayable when I start recording with Afterburner, but with ShadowPlay I can't even tell I'm recording. Using the Quick Sync plugin has the same problem as NvENC in terms of dropping performance like crazy. QS used to also give me a black video in the output file, but that was fixed with Intel driver updates. @macmyc is reporting the same problem when recording GTA IV (also a CPU-heavy DX9 game) with Afterburner: 50% FPS loss, and lower GPU usage due to CPU bottlenecking.

    Shadowplay is the best in-game recorder I've used, and this is coming from someone who owns Mirillis' solution. It works flawlessly with every game I've tried with minimal configuration needed on my end. The gameplay samples on my Youtube channel (search my user name here) were all recorded with Shadowplay, and they turned out great, IMO.

    Shadowplay default is 50Mbps, not 5Mbps.

    MSI AB does not have the performance-free nature of Shadowplay, because it does not use Nvidia IFR or Nvidia FBC to capture game footage. There is no performance hit from encoding game footage, there is performance hit from the method of capture. In this case, OBS is usually a far better solution for capture (and is also free) and can use NVENC.

    For quicksync to get the quality level of NVENC Pascal-based cards, you'd need to be using around 1.5x the bitrate, so you're looking somewhere around 75Mbps for good 1080/60 video quality (I consider 40-50 good for NVENC recording at 1080/60, more if doing 1440/60).

    On top of that, remember that Quicksync is only accessible when your iGPU is active on an intel MAINSTREAM platform. So any HEDT chip like a 5820K or 7980XE would have no quicksync access. SLI notebooks like the P870xM series have it turned off, despite the desktop chipset allowing it to be on (headless mode I believe it's called). Even if you only have a single GPU in the unit.

    No nothing like that. Just bright spots around edges of images. I notice it in DOOM multiplayer. I also notice severe stuttering on the movies on COD WW2. The gameplay is fine. I have not optimized the game though.

    I wasn't saying Shadowplay's bitrate. By default RTSS or MSI AB uses 5Mbps, I increased it to 10 Mbps. I didn't observe any glitches on my maxwell BGA using Intel QS or NVENC. On NVENC I had noticed a small stutter at the start of recording and afterwards no lags and no blocky images when running or during ultra-fast movement.
    I can use quicksync w/o any impact on CPU load and only downside is CPU temps increases to 80C instead of staying under 65C during game recording on my BGA. I'll try your bit rate settings. I always hated GFE because these days it comes with more services and telemetry w/ update notifications.

    Yeah I don't use GFE. If I have to record I use OBS. Mirillis Action! is also a fantastic recording software, but honestly, it's more convenience than anything. MSI AB would be great if it didn't use so much CPU to record with NVENC, and didn't stutter my games when I take a screenshot or record the first time.

    But when it comes to performance-hit-free recording, Shadowplay is perfection. Can't argue with that. Its options are exceedingly limited, though. If possible I'd use Action! as a primary recorder (it can mute or unmute a microphone with a button press, and has great setup options), mainly when you're in a game and something is happening so you hit that quick record button and you enjoy it. If I KNOW I'm going to record, setting up OBS to do so is probably one of the best options for performance hit, especially with single GPU only systems and recording options.

    I use MSI AB for overlay statistics though, so I wish the recording on it was better.

    If you have 1080/60 gameplay of anything remotely fast paced then 10k bitrate can't look good O_O. I use around 40K for it to look noiseless.
