I somewhat figured it was to good to be true.

hold on 2 things were going on on ngo, i dont remember a 'working on ati' thing, but i do remember allowing you to use nv as a secondary physx card after nv disabled that... which is what twl also has in his thread?

What I still don't get is "why hasn't nVidia been hit with an anti-trust suit yet over that?"

Seriously: there is no reason, hardware-wise, that you can't have a second GPU in your system where your primary is an AMD device and the secondary, nVidia, isn't used for rendering and is only used for PhysX. It is proven: you CAN have that setup. However, nVidia PhysX drivers specifically check to see if there are any non-nVidia devices in your machine and if they find any they disable PhysX.

That is pure anti-competitive bull if you ask me and nVidia should be brought before a judge for it.

Nvidia can't guarantee every version will work on hybrid setups and it'd take a lot of resources to make sure it works properly on competitors cards.
The hybrid hack doesn't work with every PSS.

As per above, every judge would throw it out of court for the reason Nvidia state, and that is that they can’t guarantee stability for such a setup, and nor should they.

Doesn’t matter if that is the real reason or not, and it might not be the reason AMD users want to hear, but it makes sense as Nvidia and AMD have a hard enough time getting stable drivers as it is, without bringing hybrid systems into the mix.

Rage is finally working constant 60 fps all the time but you need to turn off Texture Detail option.Dont forget to use cache folder (C:\Users\X\AppData\Local\id software\rage) and reset video settings by using +com_safemode 1 in shortcut.Remove the command after setting the options.And pop up is 90% gone only present after first load.Using 12.4 WHQL.The game is using approximate 600-700MB video memory.

Hi, could you just clarify the above for me? What did you mean about using the cache folder? Also, the +com_safemode 1 in the shortcut... do you know if that works on steam as well?

I'm running a 7970 in eyefinity and I thought Rage looked amazing when I loaded it up... only when I tried to move the texture popping was crazy so I didn't play it at all.

Looks amazing?! I dont think so but I do like the artistic landscape. I was disapointed with the graphics at first but now I am actually enjoying it a lot, the gameplay is great. Very addictive.

Just wish they made the graphics a little better for we pc owners...
I didnt try multiplayer yet, is it worth it?

Cheers

Actually, there is not much to "reverse engineer" when it comes to PhysX. PhysX was originally designed to run on it's own processor, a "PPU", back before Nvidia purchased it. Since then it has been allowed to run on CPU, but not any GPU but Nvidia. This is not some technical limitation of ATI/AMD hardware, but pure proprietary licensing on Nvidia's part. This is also why it's a dying engine. PhysX is used maybe what, in 1 out of every 50 games released?

Simple economic fact, AMD owns half of the worlds stand-alone discrete GPU market, most developers are not going to use a solely proprietary physics engine on many money making titles when it will alienate half of their perspective customer base. This is why Havoc is so widely used, or the developers simply incorporate their own physics into the engine.

This is sad since PhysX is a fantastic engine.

As far as CUDA goes, there is really nothing special about this either. Nvidia is simply way ahead of the game on GPU "processing" like this, but they are not the only game in town. OpenCL is on a fast track and will catch up, and I think surpass CUDA. Again, the only reason CUDA only works on Nvidia hardware is becasue it's designed that way, obviously. Where as OpenCL, as with many open platforms, do not make such a discrimination.

This used to work, then Nvidia "blocked" it, not allowing their GPU to function int he presence of non-Nvidia card. However you can get around this block easily, just Google it. I do not run a hybrid setup like this since I don't care to support PhysX when its hardly used anymore, but I know those that do and it works fine.

I agree that it's total bull, hence why I don't support it. lol

As far as how GPU Transcoding works on Rage. I run an XFX Double D Radeon R7950 Black Edition, so I can't enable it. However on this 1090T processor at 4.1GHz, I score between "great" and "excellent" on the benchmark as it is (don't recall the exact numbers and I don't have it installed at the moment), so there was no need for it in my opinion. I also did not have any streaming or texture problems.

It’s nothing really like that that either.
Hardware PhysX was intended to be run on a PPU, Nvidia bought it, and in a way use Cuda to emulate the PPU.
It’s not like you could use an ATI card as a PPU back when Ageia owned it, nothing has changed.

PhysX is dying in the same way that PC gaming is dying, as in people have been repeating the same thing for years now, but it still hasn’t went anywhere.

It’s also not a fantastic physics engine, its actually pretty crap.
CPU effects are pretty basic, and GPU effects while much more impressive are poorly optimised whether you use a CPU or an Nvidia GPU, which is why Nvidia have re-written the Ageia code from scratch into something much more efficient for multi-core CPU’s and GPU’s which by the looks of things is being integrated into the next Unreal Engine.

As for OpenCL, like most open source software they don’t tend to get enough support, this game is a perfect example of this with it being one of the few games that has chosen OpenGL over DirectX.

Why is that, can you explain it? A while back we used to see lots of more games that used OpenGL, why did they stoped? What about consoles, do they used some kind of OpenGL? I ask this because Rage was made for consoles also, correct? And id software is launching DOOM 3 remastered for the 3 platforms some months from now...

The lack of support drove developers away, DX offers a lot more and continues to grow as well as being more simplistic in a sense.

The PS3 uses some sort of OpenGL variant, but yeah it just didn’t have enough support on the PC.
A shame as I used to be a massive fan of it, but the problem with open software is that no single group has a financial interest in it.
Closed software does so they are willing to spend money adding features and giving support to anyone that wants to use it, while those using open source software are on their own.

i actually dont think CUDA in particular would 'just work' on any hardware

i bet they did all kinds of optimizations or design choices centered on the architecture of nv gpus, inside out

while opencl type would be outside in, a standard is made & the gpu companies add driver code/adjust the chip architecture to align with the spec
