This feature enables high level shading language for shaders. This feature improves performance in some particle systems. This feature provides hardware accelerated culling for objects. This feature improves the quality of texture mapping on oblique surfaces. This feature enables a wide variety of effects via per pixel programming (equivalent to DX9 Pixel Shader.) This feature enables a wide variety of effects via flexible vertex programming (equivalent to DX8 Vertex Shader.) This feature improves texturing quality by adding clamping control to edge texel filtering. This feature improves performance in some applications by using AGP for dynamic vertex transformation. This feature improves texture mapping performance in some applications by using lossy compression. This feature provides an alternate method of coloring specular highlights on polygons. This feature accelerates complex rendering such as lightmaps or environment mapping. This feature improves OpenGL performance by using video memory to cache transformed vertices. OpenGL driver version check (Current: 6., Latest known: 6.):Īccording the database, you are running the latest display drivers for your video card. Shading language version: 1.20 NVIDIA via Cg compiler Here is an excerpt from OpenGL Extensions Viewer: Renderer: GeForce Go 7950 GTX/PCI/SSE2 I am wondering if this is related to my system, I am running Windows XP Pro 64-bit, with two Geforce 7950s running in SLI. I have verified that I have the latest forceware drivers (圆4 for my system). I have hardware acceleration to full in my windows preferences, have tried uninstalling drivers, Driver Sweeping them, and re-installing. I am wondering if there is something in particular here that could be going wrong? I have been told that FurMark uses the same initialization code as the following ( ) and that this detection/initialization process is quite standard. OpenGL Extensions Viewer runs tests verifying me up to OpenGL 2.1 with good performance and 100% compatibility.įurMark, another benchmark, does not detect OpenGL 2.0 and defaults to GDI Generic. This may change with projects like nouveau, a free driver for nVidias cards.I’ve been experiencing a strange problem, where OpenGL extensions viewer detects my renderer as my video card properly (Nvidia GeForce GO 7950 GTX) but some other benchmarks/demos/games do not, instead defaulting to “GDI Generic” The user is however dependent on a driver from the graphic cards maker, and their support for OpenGL. Linux supports OpenGL, as it generally tends to support open standards. OpenCPN has been forced to disable a handful of OpenGL features for all Intel OpenGL graphics drivers on Windows, for example.įor Linux the situation is slightly different. There is currently a lot of trouble in Windows for all OpenGL applications, not just OpenCPN. Microsoft has gone from support to hostility towards OpenGL. Performance may not be improved with embedded graphics chips, often found in older laptops and netbooks. Much faster and smoother zooming and panning as well as clearer and sharper chart rendering. With OpenCPN a user with a typical modern graphic card will have an enhanced experience. It uses the graphic cards processor (GPU) and memory, to speed up applications. OpenGL is an open standard, cross platform, advanced graphic library.
