The only questions is:
Will DX9 GPUs ever deliver enough performance for whatever is to come?

Or is it just because of OS compatibility?

Are you talking to yourself?

Again: are you talking to yourself?

Most possibly: OS compatibility.

You can use a modern GPU with DirectX without any problem if there are drivers available.
For example the last Ati 12.4
Windows XP support for the AMD Radeon HD 7900 Series, AMD Radeon HD 7800, and AMD Radeon HD 7700 Series

In addition to Windows 7 and Windows Vista support, Catalyst 12.4 now also introduces Windows XP (64-bit/32-bit) support for the AMD Radeon HD 7900, AMD Radeon HD 7800, and AMD Radeon HD 7700 Series

So to use a old Operating system != old Hardware.

...good luck to you, maybe is this Friday, next one or next year, there are people like you who encourage unfinished products like this one to be flogged out to customers!

Just to stop this ridiculus and stupid discusion:

IT WAS WRITTEN ON THE BOX SO IT MUST BE SUPPORTED!!!

and since BoM uses the same engine it will support DX9 too.

If you don't like it then pay 1C all the money that they will lose to all the lawyer and people who charge them for not supporting DX9 in CloD!

!!!!!End of discusion!!!!!:evil:

Really? ;)
I am aware of that fact.
It was more about the performance difference between:
DX9OS/DX10+GPU vs DX10+OS/DX10+GPU


edit:
Makes me wonder why nobody sued them for delivering an unfinished product. Your argument is void. ;)

Guys, 1 simple thought:

If they have to support DX9 in this engine, wouldn'it be complete nonsense to drop that in the next sequel?
That would be throwing away work that is already done, resulting only in a smaler customer-base.

What is the downside of keeping DX9 if they have to support it in clod anyway?

Which is exactly why B6 just posted that it will be supported in the expansion ;)
