Why Developers Are not taking Full Advantage of PhysX and Implementing it Into Every Game

PC Authority has published a fascinating article about why consoles and the technology they have inside, mainly the GPU are preventing developers from creating more and more games with the latest and greatest in technology such as DX11, and holding back the development of PC Games. The article details the fact that game developers are trying to target the widest range of users possible, for the time being these are the consoles such as the Xbox 360 and PS3, and it’s 5 year old graphics hardware and technology. This same rule applies to why developers are not wanting to take full advantage of PhysX, because since it only runs on NVIDIA hardware they simply cannot reach the widest user base possible. Read the rest of the article here.

From PC Authority:

Even selling points such as NVIDIA’s hardware PhysX acceleration aren’t as impressive as they sound. Again, because developers need to target a wide range of end users they cannot integrate technology like PhysX too heavily into their games.

Make the game too reliant on NVIDIA-flavoured hardware accelerated physics and the huge number of people who own ATI cards are excluded from the customer base. This has led to PhysX being a means to add a little bit of extra eye candy to a game in the form of flowing cloth and extra debris, rather than being an integral part of the game’s design.

GDC 2010: Nvidia’s Sarah Tariq on Simulating Realistic Hair

GDC 2010: Nvidia’s Sarah Tariq on Simulating Realistic Hair

A cool new video has surfaced on YouTube from GDC 2010 showing Nvidia’s Sarah Tariq talking about and explaining a new DX11/CUDA demo running on the new Fermi cards that shows off realistic hair with over 18,000 strands being computed with CUDA all on the GPU. Pretty fascinating stuff, the hair color reacts realistically to light and in the demo different levels of wind can be applied to the face to show off how the hair reacts realistically. Can’t wait to see stuff like tis really implemented into games and hopefully NVIDIA releases this tech demo when the new Fermi cards are finally announced or released.

ATI + Dedicated PhysX Card Hybrid Video Setup Guide

Hardwareforyou.it has posted a really nice and in-depth, 10 minute long video to YouTube with detailed steb-by-step instruction on how to setup a hybrid PhysX system if you are running an ATI card as your main graphics renderer and want to install a second NVIDIA video card and use it for PhysX. Check it out below.

from Hardwareforyou.it:

Despite the blockade with the latest nVidia drivers that prevent the use of PhysX in the system are detected if non-nVidia cards on some forums there is a guide on how to patch the drivers to use PhysX with an ATI card. Our video will be a testimony that the block from nVidia did not do anything other than to damage the same company.
