[quote] With SoftTH you can have different resolutions but SoftTH comes with a performance hit.
My question is --- how big of a hit?... Are we talking just a little extra cpu work.. Or are we talking really making the cpu chug to keep up?
To me-- if its just a little hit on the cpu-- who cares.. With penylin(whatever they are called) coming up.. and some of the guys running 4ghtz on air with those things-- cpu hits arnt what they used to be...
Any thoughts on that paddy? anyone else?It's not a CPU hit at all. It's a GPU hit, and a hit across the PCI-Express bus as large amounts of graphical data get transferred from the rendering card to the card with the tertiary output, while the frame buffers stay synced. The hit is the overhead in using two cards to display what is really a single image. GPUs in SLI are directly linked and their is no frame buffer to sync, which is why they performs this task better (plus of course there are two GPUs rendering one scene).
