ManufacturerĭirectX Compute Support (Windows 7), CUDA, OpenCL, OpenGL 2. Therefore, the shaders have been reworked compared to the old GeForce G110M for an improved performance and battery runtime. The used GT218 core is manufactured in 40nm and based on the desktop GTX 200 architecture. MPEG-1 is not supported but can be easily handled by every modern CPU.Īs the 310M supports CUDA, DirectX Compute 10.1, and OpenCL, the shaders of the graphics processor can be used for other tasks than rendering images (e.g. The used Video Processor 4 (VP4) is able to fully decode H.264, VC-1, MPEG-2, and also MPEG-4 ASP (DivX or xVID) in hardware to minimize CPU load. Therefore PureVideo HD to decode HD videos with the graphics card is supported. The card supports DirectX 10.1 and all the features of the G 210M (as it should be based on the same GT218 core). Therefore, the graphics card can not be recommended for gamers. Less demanding games like SIMS 3 run in medium details and resolutions fluently. Some demanding games like NFS Shift or GTA4 wont run fluently at all. Modern 3D games like COD Modern Warfare 2 run only in low details and resolutions fluently. The output produced by the command glxinfo grep OpenGL is the following: OpenGL renderer string: Mesa DRI Intel (R) HD Graphics 620 (KBL GT2) OpenGL core profile version string: 4.6 (Core Profile) Mesa 20.0.8 OpenGL core profile shading language version string: 4.60 OpenGL core profile context flags: (none) OpenGL core profile profile mask. The performance of the 310M is similar to the GeForce G 210M and therefore located in the entry level class. Therefore, the 310M is an entry level dedicated graphics card for small laptops. Nvidia states that the raw performance is 73 Gigaflops compared to the 72 Gigaflops of the G210M. However, there are also newer versions that are clocked at 606 MHz and therefore slightly slower. The parameters are the same than for a texture object.The Nvidia GeForce 310M is an entry level laptop graphics card and the successor of the G 210M and therefore based on the same GT218 core with very similar clock rates (shader speed +30MHz). I just created a sampler object that enables linear filtering and 16X anisotropic filtering on any texture unit.

Now let’s see how to use OpenGL sampler objects.ġ – Sampler object creation and initialization: And good news: GL sampler states are easy to use.
#Gpu opengl 3.3 ratings code
Many things for a texture! Sampler state objects simplify the code with a clear separation between sampler states and texture data and provide a better abstraction of the GPU. Before OpenGL 3.3, the state of a texture unit was defined by a texture object (created with glGenTextures) that also includes information about texture data (pixmap). OpenGL 3.3 sampler states allow to stick to Direct3D 11 logic and its D3D11_SAMPLER_DESC structure and CreateSamplerState (D3D11 device) and PSSetSamplers (immediat context) functions (lost with device an immediate context? If so check this page out).

Sampler states or sampler objects are used to define the state of a texture unit, no matter the texture object currently bound to a texture unit. I tested today for the first time the sampler objects available with OpenGL 3.3 (more than one year…) in MSI’s Kombustor 2.2.x (in dev). This article is also available in french: Les Sampler States OpenGL 3.3: Configurer les Unités de Texture.
