How to adjust screen capture resolution ?

[cweng]

The resolution of the screen capture I got is very low. How do I increase the resolution of my screen capture ?

I guess people use third party software like irfanview and fraps to grab higher res images.

are you using the in-game "screen grab" or "capture screen" option? If so, it will grab the image at the size that you are playing it at.
