The magazine advised non-technical gamers to purchase commercial memory managers like QEMM and 386MAX and criticized nonstandard software like Origin Systems's "infamous late and unlamented Voodoo Memory Manager", which used unreal mode. Contemporary PC gaming By 1996, the growing popularity of Microsoft Windows simplified device driver and memory management. The success of 3D console titles such as Super Mario 64 and Tomb Raider increased interest in hardware accelerated 3D graphics on PCs, and soon resulted in attempts to produce affordable solutions with the ATI Rage, Matrox Mystique, S3 ViRGE, and Rendition Vérité. As 3D graphics libraries such as DirectX and OpenGL matured and knocked proprietary interfaces out of the market, these platforms gained greater acceptance in the market, particularly with their demonstrated benefits in games such as Unreal. However, major changes to the Microsoft Windows operating system, by then the market leader, made many older DOS-based games unplayable on Windows NT, and later, Windows XP (without using an emulator, such as DOSBox). The faster graphics accelerators and improving CPU technology resulted in increasing levels of realism in computer games. During this time, the improvements introduced with products such as ATI's Radeon R300 and NVidia's GeForce 6 Series have allowed developers to increase the complexity of modern game engines. PC gaming currently tends strongly toward improvements in 3D graphics. Unlike the generally accepted push for improved graphical performance, the use of physics engines in computer games has become a matter of debate since announcement and 2005 release of the nVidia PhysX PPU, ostensibly competing with middleware such as the Havok physics engine. Issues such as difficulty in ensuring consistent experiences for all players, and the uncertain benefit of first generation PhysX cards in games such as Tom Clancy's Ghost Recon Advanced Warfighter and City of Villains, prompted arguments over the value of such technology. Similarly, many game publishers began to experiment with new forms of marketing. Chief among these alternative strategies is episodic gaming, an adaptation of the older concept of expansion packs, in which game content is provided in smaller quantities but for a proportionally lower price. Titles such as Half-Life 2: Episode One took advantage of the idea, with mixed results rising from concerns for the amount of content provided for the price.
