Updated PhysX SDK 4.1 released

without comments

An updated version of the open-source PhysX SDK physics engine was just released on Github.

New features include GPU acceleration support for recently introduced reduced-coordinates articulations and immidiate mode (low level API access) support for the new Temporal Gauss Seidel solver and reduced-coordinates articulations as well.

Full Release Notes for the 4.1 release can be found here.

PhysX SDK 4.1 is available at:

PhysX SDK 3.3.2 arrives, adds GPU acceleration support on Linux

with 3 comments

New PhysX SDK 3.3.2 release is available for download.

Update March 2015: Bug-fixing PhysX SDK 3.3.3 release is available. Release Notes.

Windows, Linux, OS X, Android and iOS builds are now available for free with source code.


Among various bug-fixes, this version also features support for GPU acceleration on Linux platform (CUDA-capable devices only) and reworked documentation.

PhysX SDK 3.3.2: Release Notes


  • Added:
    • The PhysXCommon/64.dll, nvcuda.dll and PhysXUpdateLoader/64.dll are loaded and checked for the NVIDIA Corporation digital signature. The signature is expected on all NVIDIA Corporation provided dlls. The application will exit if the signature check fails.
    • Added the PxDefaultBufferedProfiler extension for simplified SDK profile events extraction.
    • PxSceneDesc::sanityBounds allows a bounding box to be set for validating the position coordinates of inserted or updated rigid actors and articulations.
    • Linux: Now supports GPU PhysX.
    • Added set/getRunProfiled() for PxDefaultCpuDispatcher to control profiling at task level.
    • Android: Support for x86 based devices was added.
    • PxProfileEventHandler::durationToNanoseconds() added. Translates event duration in timestamp (cycles) into nanoseconds.
    • Added SnippetProfileZone to show how to retrieve profiling information.
    • Added SnippetCustomJoint to better illustrate custom joint implementation, and removed SnippetExtension.
    • Added SnippetStepper to demonstrate kinematic updates while substepping with tasks.
  • Fixed:
    • Significant revision of the user’s guide. Both structure and most content have been modified.
    • PxTask::runProfiled() now takes threadId as a parameter.
    • The static pruner now issues a performance warning in debug and checked configurations when a tree rebuild occurs and the tree is not empty.
    • PxSceneDesc::staticStructure now defaults to PxPruningStructure::eDYNAMIC_AABB_TREE.
    • Linux: Switched to shared libraries.
    • Profile zone event names changed to match function calls.
    • Overlapping read/write errors will now issue a PxErrorCode::eINVALID_OPERATION rather than PxErrorCode::eDEBUG_INFO.
    • Improved SnippetToleranceScale to better demonstrate the intended use case.
    • Increased 126 characters limit for warnings on unix platforms, 1k limit on all platforms.
    • PhysXCommon dll load within PhysX dll now respects dll name. Please see the manual’s PhysXCommon DLL load section.
    • Fixed search function of user’s guide.
    • Foundation math classes now have in-place arithmetic operators (+= etc).
  • Deprecated:
    • Indexing operators taking signed integers in PxVec3, PxVec4, PxMat33, PxMat44, PxStrideIterator have been deprecated.

    GTX 680: PhysX Benchmarks roundup

    with 12 comments

    Finally, NVIDIA has officially presented their new GPU – GTX 680, built on 28nm GK104 chip, which itself is based on next-gen Kepler architecture.

    Many rumors were floating around Kepler and its physics acceleration capabilities, some were endowing new GPU with dedicated PhysX blocks, others were claiming ability to run CPU PhysX games in hardware – none of this happens to be true. Nothing special (like NVENC video encoder) for physics calculations, just general improvements to chip architecture, SM clusters, etc.

    Nonetheless, we will try to gather all available information regarding PhysX computation performance of the GTX 680, in comparison to previous generation GPUs.

    NVIDIA Kepler GPU GeForce GTX 680 Video Card Review by HARDOCP

    Interesting results – in this case, GeForce GTX 680 performance is higher than Radeon HD 7970 even with GPU PhysX effects enabled. However, we can not directly compare GTX 580 and GTX 680 due to different resolution settings.

    Alice: Madness Returns will feature GPU PhysX effects

    with 3 comments

    In a recent promo video for upcoming GTX 560 GPU, NVIDIA has spoiled next game with support of GPU accelerated PhysX effects – Alice: Madness Returns, sequel to American McGee’s visionary classic “Alice” title.

    UPDATE: Comparison GPU PhysX video

    Starting at 1:34, comparison PhysX sequences are showcased. According to the video, GPU PhysX content in Alice will include (following list may be not full) destructible environments..

    ..volumetric fluid effects (for example, oil-like fluid from damaged enemies)..

    GT 240 as dedicated PhysX card: benchmarks

    with one comment website has published a bunch of benchmarks where GT 240, low-end 40nm GPU from Nvidia, is used as dedicated PhysX card alongside with GTX 260. System used for tests.

    Performance with PhysX content, running on dedicated GT 220  (marked yellow on graph) is compared  to a single GTX 260,  calculating graphics and PhysX effects simultaneously (marked green).
