EVGA GeForce GTX 260 Core 216 Superclocked Review

EVGA’s GeForce GTX 260 Core 216 is the new version of the GeForce GTX 260. This version adds 24 shader processors to the existing 192 (192+24=216).

The Geforce GTX 260 core 216 is in fact a GeForce GTX 280, with a small chunk of memory missing, and one shader cluster with 24 shader cores disabled. Other then that, there is just no difference whatsoever.

So in general the Core 216 edition cards offer a small small step in performance over the regular GTX 260 products, but the faster clocked Core 216 products, darn it, that’s where value starts kicking in for sure.

Load All Your Game-Relevant 3D Scene Data From Various File Formats With ASSIMP

The Open Asset Import library, or ASSIMP in short, is a C++ library which loads game-relevant 3D scene data from various file formats and returns it in a common in-memory structure. The library also offers several post processing steps commonly used in realtime 3D rendering which can be applied to the imported data. Assimp supports the following file formats: .3ds, .ase, .obj, .ms3d, .ply, .dxf, .nff, .lwo, .smd, .vta, .mdl, .md2, .md3, .md5, .mdc, .mdr, .x, .mdl, .hmp.

CPU Scaling with the GeForce GTX 280

Legion Hardware has tested a range of CPUs with the GeForce GTX 280, to try and determine what kind of processing power is required to power NVIDIA’s flagship graphics card.


The test shows that with high end graphics cards such as GeForce GTX 280, one has to buy a powerful CPU in order to feed sufficiently the GPU with graphics data.

we suggest for those buying high-end graphics cards, such as the GeForce GTX 280, pick up a Core 2 Quad processor while the Core 2 Duo’s are a perfect match for mid-range graphics cards.

ShaderMap 1.1 – 3D Map Conversion Tool

ShaderMap is a small tool to convert photographic textures to height, ambient occlusion, normal, dudv, and specular maps. The free version is in command line and makes it a powerful tool to convert large amount of maps!

Okay guys, no more to tell, I’ve tried and it works well. The following images show the color map that has been used to produce the normal and ambient occlusion maps. I think this tool can be useful for your real time demos you code with GeeXLab.
