Batman Arkham Asylum PhysX benchmarks roundup

without comments

bat_bench

It’s disputable issue, is Batman Arkham Asylum that long-awaited killer-ap for hardware PhysX technology, but one is undoubtedly – supplementary PhysX effects are very well done, and can greatly increase overall game immersion level. Unfortunately,  heavy PhysX content requires appropriate Nvidia GPU, to help you understand which one – we’ve prepared an overview of PhysX benchmark articles, available on the web.

[17.09.09] Batman Arkham Asylum: PhysX or not PhysX by Revioo.com

Worth viewing article as it contains PhysX comparison videos, and benchmarks with variety of hardware (main – 9800GTX, GTX275, GTX280, dedicated – 8600GT, 9800GTX, GTX275)

[17.09.09] Batman Arkham Asylum Physx Preview by Chris Ray

This article is focused on multi-GPU (SLI, Tri-SLi, quad-SLI) configurations, and include some comparison PhysX screens too.

[21.09.09] Batman: Arkham Asylum – PhysX benchmarks with comparison shots and video by PCgameshardware.com

Contains comparison screenshots and video for in-game benchmark, and some perfomance testing for different PhysX settings as well.

[22.09.09] Batman Arkham Asylum — pořádná akce s PhysX by PCtuning

Massive and interesting overview – benchmarking results with decent amount of AMD and Nvidia GPUs, and even CPU influence tests.

[25.09.09] Batman nVidia PhysX Analysis by DriverHeaven

Probably, best article available currently. Decent descriptive part (videos included), and great benchmarking with various configurations (different CPU, varied PhysX GPU setups) tested.

[25.09.09] Optymalne karty graficzne do Batman: Arkham Asylum. PhysX, porównanie wersji PC, X360 i PS3 by benchmark.pl

Article with a small part related to GPU PhysX perfomance.

Batman Arkham Asylum CPU PhysX trick: how it works

with one comment

Maybe some of you already heard about PhysX “trick”, that allows GPU PhysX effects in Batman Arkham Asylum to run with decent framerates (~30) on fast CPU ?

There is no magic or hack here, as in this metod MaxPhysicsSubsteps parameter value is reduced to 1 (instead of 5 by default), that result in faster simulation speed, but greather decreased calculations quality.

TheElMoIsEviL has uploaded video to YouTube, that shows how well this trick works:

In the second part of this video, you can notice how papers (simulated by cloth, actually) get stuck in Batman’s character model,  their vertexes are jumping and jittering all over the screen – that’s result of simulation quality trimming.

Use this solution or not – it’s up to you, but if you want to see complex PhysX effects at their best, I’ll need appropriate Nvidia GPU, without alternatives these days.

Second part of world first PhysX textbook available

without comments

Second part of world first PhysX SDK textbook is available – unfortunally, only in Japan.

51AA6JGP1JL._SS500_51gQ63R5pvL._SS500_

Written in collaboration with Nvidia PhysX team, those manuals are not just translated PhysX SDK documentation, but complete guide, that covers most features and aspects of game physics implementation via PhysX SDK engine.

You can order your copy at Amazon.co.jp

PhysX: most popular physics library ?

without comments

Ervin Coumans, creator of “Bullet” open-source physics engine, has posted some interesting facts at bulletphysics.com recently. According to article in August 2009 issue of Game Developers Magazine, covering middleware survey results (over 100 senior developers of various development companies surveyed), Physx SDK have the lead with 26.8% in physics libraries rating, next is Havok with 22.7%, third – Bullet at 10.3%, and finally – Open Dynamic Engine at 4.1%.

Darkest of Days PhysX comparison screenshots pack

without comments

We’ve updated our Darkest of Days profile with PhysX comparison screenshots, but this time they differ a little from other comparison screens we make, as they cover all three PhysX settings types in Darkest of Days - PhysX High vs PhysX Medium vs PhysX Low.

Sample preview

You can see the rest of PhysX comparison screenshots at our Darkest of Days info mini-site

WeeklyTube Issue 2: PhysX video overview

without comments

Better late then never. Being a little busy with latest comparison videos, we’ve moved release of WeeklyTube, our weekly overview of PhysX related videos. Let’s start.

Cryostasis “Improved PhysX” Mods by PS3AuRoN89

PS3AuRoN89 is doing some research, trying to make GPU PhysX effects in Cryostasis even more physical. Current progress – increased life-time of ice particles, improved water circles, and water particles, that never disappears. We’ll keep an eye on this mod,  so you can expect complete overview as it comes out.

FallDawn by deusdaluz1

FallDawn is coop-fighting game (up to 8 players), that is build on Ogre 3D engine and is using PhysX SDK for ingame physics (like ragdolls) via NxOgre wrapper.

GPU PhysX in Darkest of Days: full version

without comments

We’ve uploaded new PhysX comparison video for Darkest of Days PC retail. Released only two days ago, this game drags player through different time periods, from Pompei to World War 2.  B-quality title, but gives unique apportunity to use futuristic weapons in the past. At least it worth a try.

Darkest of Days Info mini-site is located here
Comparison screenshots coming soon.

GPU PhysX in Warmonger

without comments

While completing profiles for old PhysX games, we’ve added PhysX video for Warmonger – Operation: Downtown Destruction title. Developed by Net Devil in collaboration with Ageia for original PhysX PPU, Warmonger is mediocre multiplayer-oriented FPS, available for free download at GeForce PowerPack #2.

Our Warmonger PhysX info mini-site is located here

Note: You can disable GPU PhysX content for this title, so it’s nearly unplayble without nvidia GPU/Ageia PPU.
