jj...ale predpokladam ze NV znizi cenu GTS640 aj GTS320 a to by zase trochu zmenilo situaciuKingP1n napísal:Uz som o tom niekde aj cital, a teraz sa to prejavilo v praxi - HD2900XT je optimalizovana pre D3D10 a v DX9 nieje az tak dobra.
Kazdopadne pokial bude cena na urovni 8800GTS tak je to lepsia kupa.

http://forum.beyond3d.com/showpost.php? ... count=5280Rys napísal:Currently it seems to be that if any GS shader is scheduled, the hardware will decrease the number of threads running for the other types indiscriminately. That's the driver doing that, though (as far as I can tell), rather than something at the hardware level.
http://forum.beyond3d.com/showpost.php? ... count=5291Jawed napísal:Eh?
G80's GS is worse than it should be (half-performance for a null shader ), theoretically, and you think that NVidia building a unified architecture is somehow surprising to ATI? Apparently the surprise is that it's not working at all well.
http://forum.beyond3d.com/showpost.php? ... count=5294nAo napísal:Well, I wouldn't be suprised if drivers can tweak or even modifying load balancing policies, it was possible on more primitive architectures so I don't see why things should change now.
Regarding DX10 performance I'd like to see tested MUCH MORE features than geometry shaders, it's not going to be the end of the world if GS implementation is not uber fast now, there's time for that, as long as devs can start to use it.
http://forum.beyond3d.com/showpost.php? ... count=5300Rys napísal:The driver can pass down what amounts to a scheduling hint based on what it's about to send the hardware to chew on.

http://forum.beyond3d.com/showpost.php? ... count=5292Jawed napísal:But Rys did say that load-balancing in this unified architecture goes to shit when GS work is scheduled.
