How to use textures and arrays in CUDA?

Could my computer be bottle necked?

• I've been trying to get the best performance out of World of Warcraft, while at the same time, getting the best performance. I can't seem to figure out why my FPS fluctuates so badly while flying through areas such as Orgrimmar and even during 25-man raids. I have heard of people with systems that are much worse than mine, and they run smoothly no matter where they are. Below are my PC specs and game settings: CPU: AMD Phenom II X4 965, 3.42 GHz GPU: MSi N560GTX-Ti Twin Frozr II, 1024 MB GDDR5, slightly overclocked RAM: 8 GB G.SKILL Ripjaws DDR3 1600 HDD: Western Digital 500 GB HDD 7,200rpm OS: Windows 7 Home Premium 64-bit Mobo: ASUS M4A77TD In-game video settings: Display mode - Windowed (Fullscreen) Resolution - 1920x1080 (Wide) Multisampling - 8x Vertical sync - Enabled Texture Resolution - High Texture Filtering - 8x Anisotropic Projected Textures - Enabled View Distance - High Environment Detail - High Ground Clutter - Fair Shadow Quality - Fair Liquid Detail - Good Sunshafts - High Particle Density - High NVIDIA Control Panel settings: Ambient Occulusion - Off Anisotropic filtering - Application-controlled Antialiasing - Gamma correction - Off Antialiasing - Mode - Application-controlled Antialiasing - Setting - Application-controlled Antialiasing - Transparency - Multisample CUDA - GPUs - All Maximum pre-rendered frames - 3 Multi-display/mixed-GPU acceleration - Single display performance mode Power management mode - Prefer maximum performance Texture filtering - Anisotropic sample optimization - On Texture filtering - Negative LOD bias - Allow Texture filtering - Quality - High performance Texture filtering - Trilinear optimization - On Threaded optimization - Auto Triple buffering - Off Vertical sync - Use the 3D application setting

• Answer:

  The lower FPS in crowded area's is common, same for raids. Check: Graphics card isn't overheating with the overclocking Lower Detail on the settings Lower Resolution Lower Anti Aliasing (This is a performance killer on higher levels) Also, on higher resolutions, you generally dont need the same amount of anti aliasing for smoothing the edges.
