They determine the amount of the graphics memory with the Intel® Graphics Driver. Unlike previous operating systems, Windows Vista* and Windows 7* have greater control over memory management. Memory can allocate up to the maximum limit set by the graphics driver. Some newer systems have an option in the system BIOS that adjusts the amount of memory available for DVMT. When the memory is no longer required, it returns to the operating system for other applications or system functions.ĭVMT allocates memory based on system needs. Video memory allocates based on the amount requested by the operating system. Many graphic-intensive applications (especially games) require a minimum amount of video memory to run correctly, or to run at all. When an application no longer needs memory, the dynamically allocated portion returns to the operating system for other uses. Graphics memory allocates based on system requirements and application demands (up to the configured maximum amount). DVMT balances 2-D/3-D graphics and system performance. What is Dynamic Video Memory Technology (DVMT)?ĭynamic Video Memory Technology (DVMT) is a method that dynamically allocates system memory for use as graphics memory.
