Ну в общем первый тест Vray 2.0 на моем 2011 х86 показал время на известной сцене Test_neoVISUAL_v5 идентичное до этого стоящему Vray 1.5 SP4 = 10 мин 39 сек. Проц i5 760
V-Ray 2.0 for 3ds Max is a complete rendering solution, which combines the power of the distinguished V-Ray rendering engine with the flexibility and unprecedented speed of the interactive rendering system V-Ray RT, now running on GPUs. V-Ray 2.0 is officially on the market starting 6th December 2010. For more information on upgrade, pre-order and pricing policies, please click here.
Major features
• V-Ray RT and V-Ray RT GPU interactive renderers are included as part of the V-Ray installation;
Shading
• VRayCarPaintMtl material with accurate flakes simulation;
• VRayDistanceTex texture that measures distances to arbitrary mesh objects;
• Dispersion in the VRayMtl material, utilizing the new support for wavelength-dependent ray tracing;
Lights
• V-Ray specific light lister;
• Directionality parameter for rectangle V-Ray lights to turn them into (textured) spot lights;
Render Elements
• VRayLightSelect render element to extract the contribution of individual lights;
• VRayDRBucket render element to show which machine rendered a given bucket in DR mode;
Effects
• VRayLensEffects render effect for producing glow and glare with support for obstacle images and diffraction;
• VRayExposureControl plugin for proper exposure of regular viewport and camera views;
Optimizations
• VRayStereoRig controller for easy stereoscopic setup;
• Shade maps for faster rendering of stereo images, DOF and motion blur through the VRayStereoscopic helper;
• Retrace threshold for the light cache
• Dynamic loading of tiled OpenEXR textures through the VRayHDRI texture;
• Integration of the various V-Ray components in the 3ds Max "Create" menu;
• Tools for calculating and rendering accurate camera distortion through .lens files;
• Faster rendering of VRayProxy objects;
• Support for proper motion blur of Thinking Particles;
• Proper blending of gizmos for VRayEnvironmentFog;
• Improved raytracing precision in certain cases;
• Render history for the V-Ray VFB;
• Load and compare images directly in the V-Ray frame buffer;
• Support for rendering of VRayProxy objects as point clouds;
• Better representation of V-Ray lights in the new hardware viewport for 3ds Max 2010 and later;
• Support for bidirectional path tracing for accurate unbiased lighting solutions;
Сделал рендер тестовый, сначала с Vray 1.5 SP 4, потом удалил и поставил на тот же комп Vray 2.0. Настраивал рендер "с нуля" и там и там. Vray 2.0 проигрывает на 13.63 %, т.е. дольше рендерит на 13.63 % с одинаковыми настройками. И по визу - тени в Vray 2.0 косячные какие то.
