2 Minor grammar tweaks
source | link

My game uses DirectX 10, and I'm having a problem where users are reporting that my game isn't picking up on their graphics card. Instead it prefers to run on their integrated Intel card, ruining performance. It's possible that this is related to Windows 8. It could also be related to mobile cards.

Until now, I've been creating the DirectX 10 device with no adapter specified (as I've seen in all the examples  / demosdemos so far), to allow DirectX to choose it'sits own adapter. Apparently I'm going to have to change that.

I already have a function which runs through all of the available adapters, and chooses the one with the highest amount of dedicated memory. That works great for correcting the problem, but is it correct in general?

Unfortunately, I cannot rely on the card having valid video output (iei.e: a monitor hooked up) as the machines affected by this problem report no outputs for the desired card.

What algorithm can I use to properly choose which adapter to use with DirectX???

Correct method for choosing the user's video cards?
