NVIDIA APEX lecture video from SIGGRAPH 2009

without comments

November’s Nvidia Developer Newsletter #49 has brought some very interesting material – 50 min. long video of “Creating Immersive Environments With NVIDIA APEX” session from SIGGRAPH 2009 conference.

apex-siggraph2009

It contains in-deph overview of all APEX Modules (FYI, APEX is artist focused framework on top of PhysX SDK), new details and demos, never shown before. Must watch for PhysX developers and people who are simply interested in PhysX future.

Dedicated PhysX GPU performance dependence on PCI-E bandwidth

with 10 comments

Using a mid- or low-end GPU as dedicated PhysX card is quite popular idea today (even among ATI owners), while PCI-E bandwidth requirements for dedicated PhysX GPU are not absolutely clear. Everyone knows, that x8 and even x4 would be enough, but what about PCI-E x1 ?

PCPOP.com has published article today, that investigates PhysX performance of GTX295 + 9800GT setup, with 9800GT used in PCI-E x1/x4/x8 cases (unnecessary pins were taped).

pci-e_adj

And, surprisingly, even PCI-E x1 usage isn’t affecting performance as much as it should at a glimpse.

BTW, users with old mobos (or lack of free full scale PCI-E slots) are asking sometimes – “What if I just put my old 9600GT in PCI-E x1 slot ? Would that be enough for PhysX ?“. Now they have some clarity. Of course, mechanical “adjustment” will be needed to make it fit, that can result in GPU/mobo malfunction, so we don’t recommend even to think about it until you are clearly sure.

Tribute to Unofficial PhysX Links & Info Page

without comments

Browsing through the web recently, I’ve found that The Unofficial PhysX Links & Info Page, oldest info website about PhysX technology (since 2005), was finally closed after several months of inactivity. Title page says:

This page will not be updated anymore.

For all things PhysX, go to physxinfo.com.

Back in early 2007 this website inspired me to start my own PhysX project, that evolved afterwards to PhysXInfo.com

Farewell !

We’ve added GPU PhysX Info profile for Sacred 2: Ice & Blood. As this add-on installs over Sacred 2 game, it has all GPU PhysX content from original title, but also adds new PhysX enhanced spells effects for new playble character - Dragon Mage. And this time more then two. As always, we’ve prepared comparison PhysX video.

PhysX Performance Overview by InsideHW

without comments

InsideHW has published fine article about hardware PhysX acceleration, with some benchmarks included.  Games (Batman Arkham Asylum, Darkest of Days and Mirror’s Edge) overview part isn’t much detailed, and only three GPUs were tested (GTS250, GTX260, GTX285), but this article is good read if you want to get in touch with current GPU PhysX posture.
