slight micro-stutter / judder @ 30 fps recording

[Montago]

While i'm thinking of it just to mention that on my laptop, i tried to record on a usb3.0 usb flash drive and it was stuttering. When i changed to record it on the SSD no stutter anymore. The usb flash drive was bottlenecking the rest.

It sounds weird to me as it can write @20mo/s

USB require a ton of CPU to work and has a high latency, which all causes the program to slow down to sync the datastream...

Im getting stutter at 1080p 30fps capture with quicksynch on playback. I cant get 60fps to work at all the playback just freezes. I will try another hdd or an ssd to see if thats the problem then i will try that valumvp thing listed here as my mobo supports it.

The system is i7 3770k, gigabyte gtx 680, 8gb ram , 1tb seagate hdd, 120 gb samsung ssd, windows 7 64 home premium.

I've been doing some tests with the new version 1.14 and the stuttering behavior changed.
In this new version, it stutters all the time when I record a game that's running in full screen (dx/opengl mode). It doesn't matter what the settings are.

But if I record the game that's running in windowed mode (still dx/opengl) it doesn't stutter anymore. Exactly the same settings and resolution as the full screen. This is an odd behavior.

Why is this happening? It's irritating if I have to run in windowed mode just for recording purposes.
I hope this gets fixed.

I know for a fact that my computer is highly capable of achieving this.

My computer is a lenovo y500.

Have you tried recording to lower resolution like 720p? Or changing game resolution to 720p?

Yes I have. I've been trying out all the options.
AVI mode is the one I use since Quick Sync is unavailable for my system. HD4000 is disabled by the manufacturer.

I have verified that this stuttering happens on my system when I am recording a game running at full screen. No matter what resolution. When I run the game in the same resolution in a window, the stuttering disappears. I've just been running my games at 1920x1080 borderless window to compensate for this. it's just like running the game in fullscreen.
