Installation instructions
- INSTALLATION STEPS (Windows 7/Vista - 32bit or 64bit):
- 1. Install the needed GeForce driver 256 package (Recommended : 285.62 WHQL).
- 2. Install PhysX Sytem Software only 9.10.0223 or later (Recommended : 9.11.0621).
- 3. Use the Hybrid PhysX mod to patch all needed files and registry values automatically.(Recommended : 1.05ff).
- 4. [optional/not needed] Use command line files to set a desired configuratio
- INSTALLATION STEPS (Windows XP/2003 - 32bit or 64bit):
- 1. Install the needed GeForce driver 256 package (Recommended : 285.62 WHQL).
- 2. Install PhysX Sytem Software only 9.10.0223 or later (Recommended : 9.11.0621).
- 3. Use the Hybrid PhysX mod to patch all needed files and registry values automatically.(Recommended : 1.05ff).
- 4. Extend the display assigned to NVIDIA GPU. Or make sure it is extended already.
- 5. [optional/not needed] Use command line files to set a desired configuration.
- Certain games or tools may require additional steps to be done to achieve compatibility with Hybrid PhysX configurations:
Disclaimer: Use following suggestions for your own risk (make a backup first)- Alice: Madness Returns - rename or delete PhysXDevice.dll library, located in game's folder (this will make driverless PhysX SDK, used in this and some other titles to recognize patched files).
- Batman: Arkham City - rename or delete PhysXDevice.dll library, located in game's folder. You may also need to extend display assigned to NVIDIA GPU (step normally not required).
- Mirror's Edge - rename/delete PhysXLoader.dll, PhysXCore.dll and PhysXDevice.dll files, that can be found in \Binaries directory.
- FluidMark 1.2. and above - rename or delete PhysXDevice.dll library, located in FluidMark folder.
Important Notes:
1. If you update PhysX System Software after using the mod, you should use it again to patch the updated PhysX files. 2. It is safe to use the mod several times - all needed files will be patched only once. 3. If you still have problems with fake displays and desktop extension, try to delete a fake display and create it again. 4. To let the mod correctly patch all needed files on x64 versions of Windows XP/2003, installKB942589 hotfix first.
FAQ:
Q: Why do we need both v1.03 and v1.05ff, which one should I use?
A: If you are not going to use anything older than 257.21 - forget about v1.03 and use v1.05ff. The mod v1.03 is intended for old 19x series and 9.10.0222 (+older) PhysX SS. If you update any component from the [old] 19x.xx and/or 9.10.0222 (+older) to [newer] 256 series and/or 9.10.0223 (+newer) - you should apply the mod v1.05ff afterwards. The mod v1.05ff will not help with 19x series GeForce driver.
Q: I applied the mod v1.05ff, but i can't find the PhysX option in NVIDIA Control Panel. What's wrong?
A: You do NOT even need to touch the Control Panel for current 256-series GeForce drivers. GPU-PhysX will work straight after you apply the mod. Don't forget to create and extend a fake display if you are using Windows XP/2003.
Q: There is something wrong with mod v1.03 window, I can only see "Info" and "backup" buttons.
A: v1.03 is having problems with GUI if you are using non-default DPI options for your display. Set it to 100% (96 dpi), like this. Sorry for this issue, it should be fixed in v1.05ff.
Q: Is there a virus/trojan/malware inside? My security software thinks so.
A: Your security software can make mistakes and thus is unreliable, just like any other security software. There is no such thing here.
Hyprid PhysX Benchmarks & Performances:
Test setup: Intel Core I7 860 CPU, Asus P7P55D Motherboard, 2GB DDR3 RAM, 32-bit Win 7 Ultimate OS.
As you may see, Batman Arkham Aylum and Darkest of Days are working fine on hybrid setup, but not Mirror’s Edge. This title needs, afaik, right combination of PhysX and GPU drivers and some manipulations with PhysX engine .dlls to get it working.
But that’s not all. People planning to add dedicated PhysX GPU to their setup are often bothered with question like “How many PCI-E lines are enought for PhysX GPU ?“. Following benchmark shows that even PCI-Ex4 slot is OK.
ATI RADEON HD 5870 + NV GT 220 Hybrid PhysX Benchmarks
Two questions may bother some people, interested in PhysX nowadays – “Are those hybrid ATI+NV PhysX configurations really working ?” and “How new GeForce GT 220 can perform as dedicated PhysX card ?“ below benchmark answer both of those questions.
System, used for benchmarks includes Intel Core i7 975 Extreme CPU, 6GB DDR3 RAM, EVGA Classified X58 Motherboard, ATI HD 5870 and Nvidia GeForce GT 220 GPUs running on Windows 7 RC7100 64-bit OS.
Three setups were tested:
Single GT 220 (Both graphics and PhysX processing)
Single HD 5870 (CPU is calculating all PhysX effects in this case)
HD 5870 for graphics + GT 220 for PhysX (using GenL Mod)
Test results:
Nurien Benchmark
| Min fps | Avg fps | Max fps | |
| Single GT 220 | 16,5 | 33,1 | 93,4 |
| Single HD 5870 | 18,8 | 42,3 | 148,5 |
| HD 5870 + GT 220 | 64,7 | 101 | 183,6 |
Star Tales Benchmark (1280×1024, 4xAA, 8xAF)
| Min fps | Avg fps | Max fps | |
| Single GT 220 | 11,1 | 19,3 | 698,9 |
| Single HD 5870 | 9,46 | 34,9 | 1213,5 |
| HD 5870 + GT 220 | 38,39 | 125,7 | 2851,2 |
Cryostasis Techdemo (1280×1024, DX10)
| Min fps | Avg fps | Max fps | |
| Single GT 220 | 9,5 | 15,1 | 43,8 |
| Single HD 5870 | 5,8 | 15,8 | 164,6 |
| HD 5870 + GT 220 | 45,7 | 75,1 | 172,9 |
Batman Arkham Asylum built-in benchmark (1280×1024, PhysX High)
| Min fps | Avg fps | Max fps | |
| Single GT 220 | 12 | 23 | 42 |
| Single HD 5870 | 13 | 21 | 57 |
| HD 5870 + GT 220 | 41 | 88 | 132 |
As you may see, single GT 220, overwhelmed by simultaneous graphics and physics processing,can’t handle latest GPU PhysX games with appropriate fps (it’s obvious, GT 220 is low-end GPU). In most cases, Core i7 975 CPU is even faster. But moving GT 220 to a dedicated PhysX cardboost framerate up to 4-5 times.
