Hi everyone,

I've read numerous posts concerning the fact that recording with Intel Quick Sync only leads to a minor decrease in performance. I find this really awesome, because a dedicated capture card, such as the Live Gamer HD, is useless to me due to the resolution of my monitor (2560x1600).

However, I do experience a great drop in FPS; in Guild Wars 2 my FPS drops from 98 to 57 FPS. Guild Wars 2 is a very CPU bound game, so I also ran a test using Crysis 2 (GPU heavy game) and again my FPS drops significantly from 113 to 73 FPS while recording. I'm recording at 1080p 30fps.

I have tested recording to a 8GB ramdisk instead of a SSD, but the performance decrease remains identical. Also, the performance when recording to AVI in comparisson to IQS is identical.

I'm sure the settings I have used are correct. The two clips below show the actual ingame drop in FPS while recording; the first clip shows Intel Quick Sync was selected.

My specs are:

Intel i7 3770k at 5.2Ghz (phase change cooling)
16 GB ram at 2400Mhz
Intel HD 4000 running at 1700Mhz.
MSI GTX 680 Lightning
Asus Maximus Gene V

All my drivers are up to date as well, including the HD 4000 drivers. All files are recorded on a Samsung 840 pro SSD.

Choosing AVI over IQS only yields larger file sizes, the actual ingame performance (i.e. FPS drop) for AVI and IQS are identical. I expected using IQS instead of AVI would yield better ingame performance. Is my assumption incorrect? Is the FPS drop that occurs during recording with Intel Quick Sync (40% drop in FPS) the way it should be, or should the performance be better than the performance I'm getting now?

dude mine pc is almost same

dammit friends using i5 3570k processor, video is smooth as butter..

but i7 3770k lag ? what is wrong ? we need patch for mirillis action ! I do not pay money for something dat not working properly

Hey Evolution, thanks for your reply. The video is actually smooth as butter, no problem there. My post is more about whether a 40% FPS drop ingame, once the record button is pressed, is normal. I expected only an insignificant (e.g. 10%) FPS drop due to the hardware acceleration by IQS. Maybe my expectations are too optimistic

I get massive drops in fps in arma 2 when I set recording to 30fps, when I increase the fps to 60 when recording 1080p I get an increase back to 60 in game however lots of studdering issues and I have lost some good footage this way.

Could you guys upload your videos so we can see the drops?

Hi Radi, the links to my videos are in the starting post. See the purple MSI afterburner FPS indicator, it clearly shows a 40% drop when I press the record button.

I found this review of Mirillis versus competitors on YouTube. It's very informative, because it shows that IQS and AVI recording both lead to identical framerates ingame. Radi, I thought that IQS (hardware rendering) in comparisson with AVI (software rendering) would lead to better performance and not result in identical performance?
