Hi Watemple,
I used to use Fraps,it got the job done.Freeware version only allows 30 seconds of record time,but if you purchase full version your not limited,file sizes are huge.The latest version does support
quad core cpu's.
Now I use Shadowplay,it's GPU driven and records in H.264,can't tell its running when recording but is limited to high end Nvidia cards-
From the Wiki;-
Nvidia ShadowPlay is a hardware accelerated
screen recording utility for
Windows PCs using
GeForce GPUs, made by Nvidia Corp as part of its Geforce Experience software. It is similar to programs like
FRAPS but uses new dedicated frame capture API which eliminates the traditional 50+% FPS loss from framebuffer capturing. It also utilizes dedicated
H.264 video encoding hardware found in 600 and 700 series graphics cards to allow the captured content to be compressed in real time to further improve performance.[SUP]
[1][/SUP] ShadowPlay can be configured to record continuously with a rolling buffer of customizable length, allowing the user to save the video retrospectively if something interesting has happened in their game, without having to remember to start recording beforehand.[SUP]
[2][/SUP] ShadowPlay currently only supports games that use
DirectX 9 or higher
