Might be worth looking into the rest of the infs

Eg nv3_dispi.inf has this section
...
%NVIDIA_DEV.13BA% = Section012, PCI\VEN_10DE&DEV_13BA
%NVIDIA_DEV.13BB% = Section012, PCI\VEN_10DE&DEV_13BB
%NVIDIA_DEV.13BC% = Section012, PCI\VEN_10DE&DEV_13BC
%NVIDIA_DEV.1401% = Section008, PCI\VEN_10DE&DEV_1401
%NVIDIA_DEV.1402% = Section008, PCI\VEN_10DE&DEV_1402
%NVIDIA_DEV.MultiView% = Section021, DISPLAY\nvMultiView
...

Which for example runs this:
[Section012.CoInstallers]
AddReg = nv_commonCoinstaller_addreg
CopyFiles = nv_coinstaller_copyfiles

Which is these:
[nv_commonCoinstaller_addreg]
HKR,,CoInstallers32,%REG_MULTI_SZ%,"nvdispgenco3235598.dll,NvGenericCoInstall"
HKR,,CoInstallers32,%REG_SZ_APPEND%,"nvdispco3235598.dll,NVDisplayCoInstall"

[nv_coinstaller_copyfiles]
nvdispco3235598.dll,nvdispco32.dll,,0x00004000
nvdispgenco3235598.dll,nvdispgenco32.dll,,0x00004000

Nvaci.inf has these sections too

%NVIDIA_DEV.139A.0963.1025% = Section016, PCI\VEN_10DE&DEV_139A&SUBSYS_09631025
%NVIDIA_DEV.139B.091D.1025% = Section016, PCI\VEN_10DE&DEV_139B&SUBSYS_091D1025
%NVIDIA_DEV.139B.0926.1025% = Section016, PCI\VEN_10DE&DEV_139B&SUBSYS_09261025

Which has sections like this:
[Section001]
CopyFiles = nv_Drs_copyfiles
CopyFiles = nv_cplInstallerCache_copyfiles
CopyFiles = nv_license_copyfiles
CopyFiles = nv_opencl_copyfiles
CopyFiles = nv_sysDrivers_copyfiles

NVSupportDisplayUpdate = 1
NVSupportGFExperienceExtendedOptions = 1
NVSupportGFExperienceUDA = 1
NVSupportNview = 1
NVSupportPhysx = 1
RegisterDLLs = nv_common_registerdll

NVNMI.inf has similar physx sections

Personally, I'd look for a 9600 or whatever was properly supported, and look in the files for EVERY iteration of the device id eg "139B" and... well, not just blindly copy it, but try and figure out what sections it runs.

NVNMI.inf :
HKLM,"Software\NVIDIA Corporation\Global\NVTweak",PhysXShowUI,%REG_DWORD%,1

In look in regedit in HLKM\Software\NVIDIA Corporation\Global\NVTweak for the key "PhysXShowUI".
If it's doesn't exist or is 0 , create, set to 1.

Thank you so much for your help, this makes a lot of sense and I was thinking about that aswell, that there is something in these files that even after installing the driver, the driver just can't relate the physX feature with my card.

Looking and comparing it with a properly supported card would be ideal, however as I said at the begining of this thread, unfortunately I dont have any spare one to go and throw it at the system and compare the files, unless someone could share me that file just for comparing purposes would be awesome and very helpful for me.

For now, sounds like a good idea, I will look again thoroughly thru other inf files and the regedit aswell and check if I can find any solution there.

Thanks again.

Oh, I didn't mean find an actual card. I meant find the known working card in the inf files and follow what they do.

Oh sorry😅, I see what you are saying my friend, well for reference I think I have to compare the device number with lets say the 9800 gtx, which was the GPU that the game ask for in the recommended settings and also I know that GPU was PhysX compatible because it has 512 Mb of vram . I just would have to compare the NVIDIA_DEV.17C8 which stands for the GTX 980t ti with the watever DEV id has this other card and then compare.

I will check this and post my result in case is helpful for someone else with my particulary case.

Thank you my friend 😀

Ok, so find every reference to that number in all the infs.

As a quick hack for testing, you can try just replacing that number with yours in all of them and see if it works.

If yes, you can either look deeper and figure out what is different, or just save it and move on.

If it's doesn't exist or is 0 , create, set to 1.

So I was able to check all the files as you told me, I did the modifications of all files accordingly and then I manually created the key for the PysyX option in the regedit and now Im able to see the configuration for the physx in the control panel however I does not let me choose the GPU to use this feature, it only goes to CPU or it goes Auto( which at the ends it uses CPU for physyx) not sure what else to do. Now I have a question for creating the key in the regedit should i create key, string, binary, DWORD, multi string, expandable?.

For this case as show in the picture I created string but I have to put many binary numbers, with dword is limited to just 0 or 1 i tryied that to but still does not let me choose the gpu, when i press apply it goes to cpu.

I also tried the driver version 344 that cyclone (thank you btw) told me to try, modified that file but still not working 😢.

So I am at a dead end now, dont know what else to do.

Does that driver work for anyone else with a different card?

Which card?
It's most likely a dword

At this point, I would suggest performing a clean install of WinXP + SP3. Something likely went wrong when installing the various driver versions and/or PhysX updates during your previous attempts.

As mentioned before, it shouldn't be necessary to do anything else besides installing the Nvidia driver with the PhysX component selected. As for the driver modifications, I'm pretty sure I changed a single INF file in like two places to add my GTX 970 to the 355.98 driver. I certainly didn't create any custom registry keys or whatever. If I remember correctly, I simply followed the instructions from this website to perform the modifications.

Thank you Joseph, I think this would be my very last resource, do a fresh reinstall of the system and do a clean new install of the modified driver, maybe that helps as you said. I will do this when I have time and post back if I got any positive results.

Thanks again.

I tried but It kept chosing the CPU as the physyx hardware to use in the Nvidia control panel.

It did work for Josep, he is using a Gtx 970 on his windows xp machine and he only modified one inf file in the whole process.

At this point I think I have no other option than do what he is saying which is doing a re-install of Windows xp, and do a fresh install of the nvidia driver modified.

However I dont have anytime for that now because Im working on other projects now, but as soon I got the chance for this I will do it and post my results here, and see if it worked.

Did you try running Display Driver Uninstaller (DDU) yet? It was common to use back in the day to completely wipe out AMD, Intel, and NVIDIA drivers, including all files, registry entries, etc. Then you could load new ones without needing a full OS reinstall.

Thats a good catch, I will try that option as well before doing a full reinstall.

Thanks

Do you have another nVidia graphics card to try?

Not at the moment, this Gtx 980 ti is the only one I have, I used to have a more driver compatible GTX 960 card but never use it in my windows xp system, I was planning to but at the end I just decided to go more overkill and dropped a 980ti in the system. Unfortunately I gave this 960 out so there is no option to tried with this card. I will do a swipe of drivers first before doing a freshly new reinstall of the OS.

What is your deviceid again?

Yes thats correct, and all the instalation files reference for this device is associated to section 8 in the inf file aswell.

I haven't spent much time on it, but these are the infs which appear to reference the 960. (device 1401)

Thank you so much for taking the time to do this, you know what? its funny but when I was modifying the files before I was wondering the same thing, which one could be my subsys, I just replaced the device id but not this one, probably that was why It did not worked, actually I forgot to ask you about the subsys but now I know that you can find that info in the gpu-z 😅.

Anyway I will try this as soon as I got the chance and let you know if it worked.

Thanks again myne

Hopefully it works
