GET up to 34% performance increase in DX10 games

[TheMailMan78]

but there is a benefit for ATI users. DX11 enables Stream processing for all applications on windows which is like Microsoft CUDA and will have better performance if you have ATI card

Ok so not much will change in the end. Only programs that utilize stream. Has anything used stream yet in this fashion?

So has anyone tried it out as yet??

 

[ChiSox]

Hey Saik....

So I have a rig with 2 3870's in Crossfire and a rig with 2 8800gt's in SLI....

would I benefit more if I used 1 3870 and 1 8800gt for physics???

the crossx machine uses a E8400 and the SLI a q6700

So has anyone tried it out as yet??

Yes...I did...just before installing SP2 RC ... (the belly went inside out - shame on SP2 :shadedshu)

Yes it was working....Crysis did get a desent performance boost...hell - it was allmost playable.. hehe

 

[devguy]

I just tried to try it out in Vista x64. I downloaded the inf, backed up the original inf in the drivers/lh6a_inf directory and copied in the new one (catalyst 9.2, btw). Then, I opened up device manager and tried update device driver and chose the modified one. It is not digitally signed (obviously) and I received a warning, but then I got this picture and it won't install:

I hope we don't have to install it using the CIM, cause if we do, I'm not even going to bother, unless someone else tries it out first and has great results.

For windows vista 32bit guys

For people who wanted to know, how it works. this is a post by a member who tested it

First of all congratulations for the driver tweak. BTW no one tried it yet??

Now, about CUDA and PhysX there's a lot of inacurate, incorrect and some borserline false info giving here.

- The only game with GPU PhysX released to date is Mirror's Edge and when GPU PhysX option is dissabled, there's no offloading of anything to the CPU. When dissabled both Nvidia and Ati cards have exactly the same CPU usage.

- CUDA can't offload ANY work out from the CPU unless the program was especifically programmed for that purpose. CUDA for instance, has to be initialized in the program itself to work, just as you have to initialize DirectX or any other API.

- CUDA and OpenCL and STREAM are virtually the same thing (the three come from Brook+), just that each of them have their own sintaxis. There's no such thing as Nvidia cards run better CUDA than they do OpenCL, nor Ati cards run better STREAM. There's going to be differences? Yes of course, some little ones, but if a Nvidia card is faster with CUDA than a comparable Ati card with STREAM it wil be so with OpenCL and viceversa.

- PhysX is a physics API and engine first, which is exactly the same as Havok, and on a second level has an optional interface to comunicate with CUDA, with Ageia physx card or even PS3's SPEs. By default it runs on the CPU just as Havok, it's required a condition to run it in other platforms.

- Because PhysX is independant from the platform, and GPGPU solutions are so similar between them there's not going to be any problem to run PhysX through OpenCL or DX11. It took Nvidia 2 months to adapt PhysX to CUDA, it will take about the same (or less) to adapt it to OpenCL.

- AFAIK DX11 will not have a physics engine implemented similar to Havok or PhysX. It will just have some shaders and extensions to make things easier, but won't be any different from D3D. You still have to make the renderer and game engine, right? The same will be with physics. DX11 will make possible GPU accelerated physics, but companies will still need an engine and will most probaly outsource to Havok or PhysX as they have always done. Now who you do prefer to dominate the physics world and future is your own decision: Intel (they own Havok) or Nvidia? And don't be naive, if you think that Nvidia would make PhysX run better on their hardware, think that Intel will do the same (and that hardware is Larrabe, with nothing in common with Ati/Nvidia GPUs). Intel has a much longer and intense history with antitrust behavior, plus it's like 10 times bigger, omnipotent and omnipresent, so think it twice.

I'm getting ready to install. I got Crysis loaded. Nothing else that's DX10 unfortunately.. Right now I get about 23-27 fps DX10 using Jrob's Ultra Quality and the TOD mods.

P.S. Sorry for doubting you before man, I would've like some info on how it was done, ex. what you tweaked etc.

 

[spearman914]

Nvm trying it. Will report back.

As I recall it Warmonger was/is a game with GPU PhysX (or is it only working on Ageia´s original PhysX card/processor? and not the actual GPU?)

 

[DarkMatter]

AFAIK is only a demo (or a "game" with just one MP level), at least the one you can download from Nvidia's power pack is. I never thought it to be a game.

 

[EastCoasthandle]

I don't think i have to elaborate . you understood it right, except that not CUDA but Physix bottlenecks the ATI rig

Ok, thanks for the information.

Well yes...it only has one multiplayer level (I was beta tester on that game, via Ageia´s forum, because of my ASUS PhysX P1 card with astonising 128 MB memory) but it´s still a game though...one level....but still a MP game

 

[ShadowFold]

Umm yea this doesn't work at all with Crysis. I get the same FPS.. I even turned down some settings and it doesn't run above 20fps.

 

[stuartb04]

didnt really have any noticeable difference either

shame.but thanks

 

[SKD007]

you have to uninstall the previous driver and restart the computer and then install this one. dont change any settings on CCC or ATT. the tweak effect will be lost and if u have ATT. this will not work. its works m8. u r doing some mistake.. re do it and tell me.. i will tell u what u can try next

Just tried it and got a 3fps in minimum fps and 5fps in average fps increases. this was tested in crysis. thx mate. But I can't tweak any CCC settings.

 

[EastCoasthandle]

Looks like there are some improvements with this tweak.

 

[btarunr]

Microsoft is using something called OpenCL in DX11 which is supported by both ATI & Nvidia

No it isn't. Microsoft is coming up with its own proprietary GPGPU interface, which ofc, is available for any compliant GPU vendor.

OpenCL is driven by an ARB (architecture review board, a SIG), and already exists.

5FPS in crysis Is good for me ....

please do check other games pls.. one member clams 11FPS boost increase in clear sky.. can some one confirm and i got feedback tat the tweak is working better on low end cards like 3 series

here is a guy... i don't understand how he is getting such a boost...

http://www.ngohq.com/76673-post20.html

Here is a test on GTA4 click here



Well, here are the results.

SKD driver

11989, 331407, 20, 58, 36.176
14717, 392482, 26, 55, 37.497
1337, 28227, 35, 62, 47.366
6227, 184480, 25, 51, 33.754
4603, 134813, 26, 57, 34.144
5537, 172472, 20, 51, 32.104
7875, 207050, 24, 73, 38.034
2953, 80166, 28, 49, 36.836
10458, 282407, 25, 57, 37.032

Here are all the benchmarks and from what I know of GTA IV me thinks it's safe to assume that the first two and last three results are the most conclusive. The third one is just over the top, the following three are probably skewed becasue of the memory leak, so I restarted the game and took three more benchmarks.

When I say benchmarks I mean fraps benchmarks while running through the same part of he town during the same time of the day in set weather conditions causing mayhem and destruction.

All in all, around 38. A good result.

Reports say, After installing SKD driver and reinstalling 9.2 default Driver . you still see some FPS improvements so test your 9.2 default before installing SKD driver. don't test default driver after installing mine

This for 64 bit to?

 

[InnocentCriminal]

Ooooh, 3 series. I'll have to send it to my GF. I miss my 3850 (AGP) that's something you (or I) could add if you haven't already. AGP support.

Bit sus, can sum1 scan it for viruses?

I can do it if u want, I have a laptop with hard drive failures reported I can offer to sacrifice.

Can u please check and let us know about the performance.... i would be happy to know
