Video recording: hardware usage?

Hey I'm just curious to know what a video recording software such as Fraps actually uses in your computer..is it RAM, CPU, graphics or harddrive, perhaps a combination?

Reason I'm asking is because my comp setup of the following:

Core 2 duo 3,16ghz
4 gig ram
geforce gts 1024mb

.. cannot run 3D games without small but really annoying choppiness.

This make me a really sad panda, Any tips on what component needs buffing? Or if there is any software fix to help with the issue?

Hard drive and CPU take the biggest hits.

Ideally, you want to record to a separate empty hard drive, that not your system drive or the game drive.

A dual core should be fine, but again, ideally for video recording/streaming at high resolutions you want a quad.

Well my CPU is the best component of my comp... so i guess my HD must just be really fricken bad :/

Does video recording software even take use of 4 cpus?

i just realized that you're european, and so its actually 3.16 in the American notation.

The only reason i can think that your comp can't handle is it that you're being configured to write to disk rather than ram, (which makes sense) or that your resolution is insane. Probably a combination of both. A raw recording of a 1440x 900 video at 32 bit color and 25 fps, is... well, I'll let you do the math but it's something on the order of like 100 mB/s... A typical hard drive bottlenecks somewhere between 10 and 100 mB/s. That could very easily be your bottleneck. Halving the resolution should do the trick.

I never had success with video recording softwares but I noticed that it's better if you have 2 hard drives. For Example if Starcraft is on the C drive, it's better to have Fraps write to D drive.

I suppose that getting a SSD would solve a lot of problems.

Or if you use something like Camtasia and select a codec like x264vfw, it'll require less Hard Drive usage as long as you have enough cpu power.

SSD would solve the problem. But they're crazy expensive.

Yeah you need a good ssd else you might as well get a good normal hdd becuase cheap ssd their sustained write times are not that good. throwing down 300 for video recording seems a bit ridiculous anyways.

Might as well raid 2 or 3 seagate 7200.12 or the new samsung's drives together for that price. seriously i could get 3 seagates .12 750gb for like 170 still be cheaper then a good ssd although not as quiet.

Well i have 2 7200.12 in raid each can do sequential writes at 135mb/s giving me an avg of 240mb/s(via crystaldiskmark) in my raid set up for only 120 bucks which can do 1920x1080 at 30fps pretty easily, the problem with using a compression to get a recording while playing games is that it zaps cpu power away from the game to the compressor which is fine if you have like a 200-300 dollar cpu that isn't fully tasked by the game anyways.

Gosh so much money spent just to be able to have lag-free recordings.. Im gonna go with T.O.Ps suggestion of trying out Camtasia with that particular codec..

Thx for all the replies
