GPU PhysX in Hawken

with 12 comments

GPU PhysX integration in Hawken, free-to-play mech shooter from Adhesive Games, has a long and yet ongoing story – preliminary PhysX effects have emerged in Alpha and Closed Beta versions, then they have undergone a significant overhaul in Open Beta release.

Update: Hawken – GPU PhysX Profile

Update #2: Upcoming PhysX features in Hawken – Destructible Environments

And now, recent “Raider” update has added a set of new, APEX Turbulence based particles effects, and we think that GPU PhysX support in Hawken has grown up enough to be reviewed.

APEX SDK 1.2.3 is now available

with 10 comments

NVIDIA has released an updated version of APEX SDK.

Update: APEX SDK 1.2.4 is available

New version is compatible with latest PhysX SDK 3.2.3, and also includes a bunch of bug-fixes and some minor new features.

APEX SDK 1.2.3 – Release Notes

  • APEX Framework 1.2.3
    • NxResourceProvider is now case-insensitive by default. To get the old case-sensitive behavior, set resourceProviderIsCaseSensitive true in the NxApexSDKDesc.
    • Fixed issues with re-entrant read locks.
  • APEX Destruction 1.2.3
    • GPU rigid bodies are no longer supported on pre-Fermi hardware.
    • Added actor synchronization filtering by damage event depth and fracture event depth.
    • Added NxDestructibleActor::setDeleteFracturedChunks() to tell a destructible actor to delete its fractured chunks instead of simulating them.
    • Added NxUserDestructibleSyncHandler::onPreProcessReadBegin() and NxUserDestructibleSyncHandler::onPreProcessReadDone() callbacks.
    • Edited NxUserDestructibleSyncHandler::onReadBegin() callback. Removed NxUserDestructibleSyncHandler::onSwizzleDone() callback.
    • Added NxDestructibleActorSyncState struct. Edited NxDestructibleActor::setSyncParams() method.
    • Edited NxDestructibleActor::setHitChunkTrackingParams() method.
    • Added new NxDestructibleAssetStats: maxHullVertexCount, maxHullFaceCount, chunkWithMaxEdgeCount.
    • NxDestructibleAsset::createDestructibleActor() renamed to NxDestructibleAsset::createDestructibleActorFromDeserializedState().
    • NxDestructibleActor::getPartTM() renamed to NxDestructibleActor::getChunkTM().
    • IExplicitHierarchicalMesh::IConvexHull::reduceHull function removes vertices from a convex hull until the given limits are reached (after cooking).
    • Added both the destructible actor pointer and the chunk index to the NxApexPhysX3Interface::setContactReportFlags() callback when PhysX 3.x shapes are created.

Full GPU PhysX support will be coming to Hawken in March 5 update

with one comment

Online free-to-play mech shooter Hawken will be getting a major update on March 5. This so-called “Raider Update” will not only introduce the new Raider mech with new weapons, a new Facility map and plenty of balance tweaks, but will also add an option to enable full-scale GPU PhysX effects.

Update: GPU PhysX in Hawken – review and benchmarks

PhysX High Option: PhysX particles can now be set to High in the Video Settings menu. High (NVIDIA Only) Option will be grayed out if your computer does not meet required specifications.

Hawken High PhysX

So far, the game includes only a set of basic PhysX particle effects (that can be called “Medium” PhysX settings) such as impact debris and chunks, while “High” PhysX option should also enable APEX Turbulence based particles.

Be sure to check back on for effects comparison video and PhysX review after the update.

PhysX SDK will replace Havok in The Witcher 3

with one comment

A few years ago, CD Project Red has licensed Havok physics engine and animation system for upcoming game titles. As result, the highly acclaimed The Witcher 2: Assassins of Kings title was using Havok based physics.

Update: The Witcher 3 will support GPU PhysX, now officially

As company’s next generation REDengine 3 was announced, it would be natural to expect that future games utilizing this engine, such as The Witcher 3: Wild Hunt, will continue to rely on Havok technology.

However, in a recent interview with PCGamesHardware, it was revealed by the developers that PhysX SDK will be used in The Witcher 3 as the physics engine (and this was confirmed by our sources as well). In addition, NVIDIA APEX integration will provide additional features such as cloth simulation and realistic destruction.

As of yet there is no information if GPU acceleration will be supported by The Witcher 3 or if other CD Project Red projects, like Cyberpunk 2077, will use PhysX based physics too.
