I want Nvidia physX engine in Nexuiz and/or Zymotic

This is samples of use:
Old Ageia physix in cellfactor revolution ( free demo game - not for download now )

New Nvidia physx demo in Warmonger ( free demo game - http://www.warmongergame.com/ )

Nvidia PysyX you can run on Nvidia 8xxx , 9xxx and GT200 serises but you need new drivers.

UT3 have special designed maps for Nvidia PhysX

All what you need you find here.

I dislike the idea to have effects just for some players besides (could not find it quickly) something tells me the SDK licence will not be compatible with the engines GPL licence..

This is new Nvidia project . We must wait for all SDK.
But i think , is posible to speedup nex graphic adding particle systems efects to environment (rain , fog , blowups , water ) without negativ efects for players without physX acceleration.

Its a fast paced deathmatch game, it really doesnt need realistic physics in the slightest.

I'm pretty sure you need to pay a licensing fee to use physX in a game...

Not realistic , but impressive.
Now physX is something new , but we must look in to future ,becouse that will be standard in games.
Without evolve nexuiz will die...

Nvidia wrote:The NVIDIA PhysX SDK (binary) is 100% free and available right now for download by developers. In addition to the free software offering, NVIDIA offers additional support plans and a paid license program which enables developers to modify the SDK to suit their needs.

The binary version of the PC SDK is offered at no charge as outlined below. Source code (for integration purposes) is available for a fee as provided below:
Free SDK Package:

* Most Current PC Binary
* Commercial & non-commercial use on PC
o Available for Windows & Linux
o No PhysX hardware optimization requirement
* PS3 platform (through Sony pre-purchase)

Licensed (Source Code) Package (US$50K Per individual application)

* Xbox 360 Source
* PC Source

If we need money , we can ask users for free donation.
Nexuiz is for users not for money.
If they want PhysyX we can give it.

It doesn't matter that the SDK is free. For content to be included in Nexuiz, it must be licensed under the GPL, and this is not open source.

Exactly. If it's not GPL, the developers won't use it.
Even the Havok physics are more likely to be added into the engine, since they're Open Source now afaik. But I don't expect this to happen in a short term...
I can't remember any Quake-engine-powered game using Havok physics though Are they even compatible in some way?

What about this thingie btw?

Nice . "Open Dynamics Engine" is an open source.

Games using ODE to simulate physics:
S.T.A.L.K.E.R
Call of Duty 4: Modern Warfare
BloodRayne 2
and more.

I go to ask general creator about acceleration ODE on new Nvidia drivers just for info for me and him :]

There are several open-source physics engines out there - Bullet, ODE and others but they're CPU hogs. For multiplayer they'll need fairly powerful servers to run in a crowded game as servers seldom have PhysX or GPGPU hardware. The hosting fees for such powerful servers are prohibitively high for many Nexuiz server operators.

IMO There are more significant issues to spend time and effort on - optimising the renderer, improving the game assets, improving the bot AI, getting DP/Nexuiz to make efficient use more than one CPU core, etc. I think these are more important because as far as game mechanics are concerned, Nexuiz is much more of an old-school shooter than a realistic combat simulator. As such uber-real physics isn't a major requirement.

Does not work license wise so no. If they released some kind of driver that allowed the free software based systems to run in hardware on a graphics card then it would be possible, but that's unlikely.

It will take a huge toll on the GPU. I am running UT3 at almost all Max at a smooth rate of 60fps but when I played Nvidia's physx maps. It dropped to unplayable framerate and as someone said above, Nexuiz was never about realism.

Implementing it would be cool though.

What graphic card you have ?

Nvidia PhysX is designed for 8xxx or beter .
And you must remember about downloading new drivers and eneble PhysX in control panel.

8600GT which is overclocked to almost match the performance of a 8600GTX. Not a particular strong card in the series but its cheap .

I have latest drivers and already tried tweaking around. Hardware physics in UT3 seems to take a crazy toll on my GPU.

Without it, I can get an average of 60fps but with it enabled, single digit. -Shocks-

When (if) physx becomes de facto standard, then maybe someone will do it. What I've understood until now Nexuiz is made to be available to as many players as possible and not for the ones running latest and greatest. If you have coding skills, you could add physx support to DarkPlaces and I believe LordHavoc will accept this.

Nexuiz at least now isn't real time combat simulator, it's more like traditional old school shooter, which can be played competitively. If I am informed correctly, It's uses Newtonian physics for body and gibs simulation. Of course, picking things and destroying environment would be fun, but it won't make you score more frags. Some might not agree, but imho it's the main purpose of this game (gameplay wise)

In addition, visual effects such as snow and rain realism does not depend on physx (at least, how I understand it), but on the available OpenGL functions your graphics card can support. Yes, it would be fun to have those, but I don't think it's the main priority now.

Personally I find fancy graphics very distracting when playing. I was playing Nexuiz on my friends computer (8800gtx, Quad core, 4gb etc.) turned up full and half the time I couldnt aim because I kept getting distracted by the prettiness.
