EVGA GTX 275 CO-OP PhysX: Under the Hood

without comments

EXPreview.com website has published detailed pics of EVGA GTX 275 CO-OP PhysX – card with exceptional design, which combines two different GPU,  G200 (GTX 275) and G92 (GTS 250), on one PCB.

55nm GT200b graphics-rendering chip (left one on a pic below) operates at a 633MHz core, 1296MHz shaders and has 896MB of GDDR3 memory, running at 2268MHz. 55nm G92b chip (right one), fully dedicated to PhysX processing,  runs at a 738MHz core, 1836MHz shaders, and has 384MB of 2200MHz GDDR3 memory.

Recent PhysX benchmarks overview

with one comment

Recently, bunch of PhysX related articles have emerged on several chinese websites, like yesky.com or EXPreview.com. They all have similar structure and idea – benchmarks of Nvidia GPUs vs ATI GPUs in games with hardware accelerated PhysX content. Typical result is looking like this..

bench_ati_vs_nv

.. and can mislead inexperienced user – “How can it be, that low-end GT240 outperforms hi-end HD5850 ?! Is GT240 better thus ? I’ll buy it as Christmas present instead“. Answer is simple – in ATI’s case supplementary PhysX content is calculated on CPU, while accelerated on GPU in Nvidia case. Therefore, playing with extra GPU PhysX effects enabled on ATI GPU will result in low fps regardless what setup you have – old X1800XT or two HD5970 in crossfire.

Appropriate Nvidia GPU – it’s the only way currently to enjoy games with GPU PhysX support. Is it worth ? It’s up to you to decide. And don’t forget compromising solution -  officially unsupported, but popular Hybrid PhysX systems.

Sequel to Batman: Arkham Asylum announced on Spike VGA

without comments

Sequel to much-talked-of Batman: Arkham Asylum title was announced yersterday on Spike’s Video Game Award Show. No additional details were revealed except short trailer and teaser website – http://www.arkhamhasmoved.com/

Original Batman: Arkham Asylum is one of the best titles in GPU PhysX games library, lets hope Nvidia won’t loose opportunity to enhance Batman’s sequel with even greather hardware accelerated PhysX content.

Back to Hybrid PhysX systems: new benchmarks

with 3 comments

It seems that today Hybrid ATI+NV PhysX systems (ATI GPU for graphics, Nvidia GPU for PhysX) are even more popular than Ageia PPUs in their time. Not officially supported (and chased) by Nvidia, such configurations are possible using custom patch.

This time, our colleagues from PCgamesHardware.de have published results of Hybrid PhysX tests in Batman: Arkham Asylum built-in benchmark.

Physx_hybrid_bench

To built a Hybrid PhysX System, you’ll need mobo with two PCI-E slots (regardless to SLI/Crossife support; PCI-Ex8/x4 is enough for PhysX), appropriate Nvidia GPU (something like 9600/GT240), Win XP/Win 7 OS and PhysX mod 1.02, which you can download here.

Installation instructions – Link#1 | Link#2 | Link#3 (Please note that most of them refer to old PhysX mod 1.01 – use 1.02 mod instead, download link above) | Link#4 | Link#5 (video guide) | Link#6 (Italian video guide) | Link#7 | Link#8 (detailed) <- it’s recommended to start from newer links.

pXent PhysX wrapper: realtime fracturing without APEX

without comments

We are keeping an eye on promising PhysX SDK based projects, like RayFire Tool, PhysXforQuest wrapper, and – pXent PhysX SDK wrapper for 3D GameStudio engine. This time a new impressive feature was added – realtime generation of fragments for dynamic fracturing and destruction of objects.

Of course, it’s still not APEX Destruction level, but close enough.
