GTX275 Set for April 2nd Launch; Specs “confirmed” – Ambient Occlusion to be added to WHQL Geforce 185.20 drivers

It appears that all of the speculation about GTX275 has been confirmed by one of our sources.  Accordingly, we can expect a paper launch with expected clockspeeds of 633 MHz core/1136 MHz memory; and shader information previously leaked about 1404 mhz were evidently spot on.  There are still some conflicting reports which place its memory speeds at 1134 MHz.

 

More interesting perhaps, is the ambient occlusion that will be added to the new GeForce 185.20 drivers. Although we have seen the betas, it is now confirmed that they will be released together with the GTX275, and should net approximately 5-20% improvement in several games.  And of course, they will add ambient occlusion.  It is reported in Half Life 2, an old game,  it gave some nice shadows, but it also took a performance hit of about 20%.  Evidently Nvidia also had a example of ambient occlusion in World in Conflict, but they would not specify the performance hit.  We have also seen additional SLi-AA modes which is a welcome new addition introduced by these new GeForce drivers.

 

We can also expect Nvidia to be releasing a new power pack, with some PhysX demo’s. 

 

Stay tuned.  Much more to come.
