I use Fraps when recording my gameplays but it chops off like 5-9 FPS and makes the recorded video laggy. Is there any tool I can use to record gameplay without a resulting loss of much FPS?

Since any program i have ever heard of uses some system resources, a program like the one you're asking for might be impossible. –  RedRiderX Nov 8 '11 at 20:58
    
sorry, you may claim otherwise, but this question is a de facto duplicate of How can I record demos of my gameplay? - however, your additional requirement "without loss of FPS" leads to the interesting hardware solution, which would also be a valid answer there –  Zommuter Nov 20 '11 at 9:27
    
@TobiasKienzler Either way it still fits in the scope of Gaming.SE and still remains a valid and open question. –  Mob Nov 20 '11 at 9:45

You won't be able to do that with a software solution - at least not for any graphically intensive applications. If the application is rate-limited to 60 fps, but could as well run at 200 fps if allowed to, recording won't make a difference, of course ...

There are hardware recorders available, including those for HDMI. There are even internal hardware recorder cards available (like the Hauppage Colossus). I'd suggest looking around on sites like Tom's Hardware or the Audio/Video Stream Recording Forums for reviews and detailed help.

you should also post the hardware solution on gaming.stackexchange.com/questions/392/… –  Zommuter Nov 20 '11 at 9:27

You could use a video camera pointed at your screen. It will cause 0 FPS drop, however the quality will be terrible.

Alternatively, check out Blackmagic Design Intensity Pro but be aware it is limited in resolution to 1920x1080.

I was originally thinking you could use VNC to clone the display to a separate computer that was running FRAPS where you could record it, but I don't think VNC can get the hardware accelerated images, and also doubt your network is up to transferring that quantity of data smoothly.

Martin Sojka has the right of it, it will be a hardware issue to increase the performance. The only other things you could do is stop all background processes before starting your game and FRAPS and lower your game graphics etc. so it will run faster.

I haven't tried it myself but I've heard good things about using dxtory instead of FRAPS.Apparently dxtory doesn't stifle framerate as much but uses more disk space for files, pre-converting to a standard format. So if you have storage over performance I'd give it a go.
