Before Direct3D 10, new versions of the API introduced support for new hardware capabilities, however these capabilities were optional and had to be queried with "capability bits" or "caps". Direct3D 10.1 was the first to use a concept of "feature levels" [1] [3] [6] to support both Direct3D 10.0 and 10.1 hardware. [3] [7] [8]
DirectX 12 is supported on all Fermi and later Nvidia GPUs, on AMD's GCN-based chips and on Intel's Haswell and later processors' graphics units. [ 60 ] At SIGGRAPH 2014, Intel released a demo showing a computer generated asteroid field , in which DirectX 12 was claimed to be 50–70% more efficient than DirectX 11 in rendering speed and CPU ...
Emulation of SGX was added to an experimental version of the QEMU system emulator in 2014. [10] In 2015, researchers at the Georgia Institute of Technology released an open-source simulator named "OpenSGX". [11] One example of SGX used in security was a demo application from wolfSSL [12] using it for cryptography algorithms.
Meltdown exploits a race condition, inherent in the design of many modern CPUs.This occurs between memory access and privilege checking during instruction processing. . Additionally, combined with a cache side-channel attack, this vulnerability allows a process to bypass the normal privilege checks that isolate the exploit process from accessing data belonging to the operating system and other ...
Direct3D 11.0 features include: Support for Shader Model 5.0, Dynamic shader linking, addressable resources, additional resource types, [72] subroutines, geometry instancing, coverage as pixel shader input, programmable interpolation of inputs, new texture compression formats (1 new LDR format and 1 new HDR format), texture clamps to limit WDDM ...
The System tab displays the current DirectX version, the computer's hostname, the operating system's version, information on the system BIOS, and other data.The DirectX Files tab displays information about the versions of specific DirectX system files, which are portable executables or dynamic-link libraries (DLLs).

One of the limitations of WDDM driver model version 1.0 is that it does not support multiple drivers in a multi-adapter, multi-monitor setup. If a multi-monitor system has more than one graphics adapter powering the monitors, both the adaptors must use the same WDDM driver. If more than one driver is used, Windows will disable one of them.
