Detonator 4 Improvements?

According to NVIDIA the new Detonator 4 drivers (which support all NVIDIA GPUs as well as the nForce’s integrated GPU) include DirectX and OpenGL pipeline optimizations.  While we couldn’t get much information about the specific optimizations included in the Detonator 4 drivers, we did find out the nature of some of the OpenGL enhancements.

The Detonator 4 drivers include a new OpenGL 1.3 ICD. Here’s what NVIDIA had to say about the driver improvements:

Increased Data Bandwidth

Detonator 4 Software’s new OpenGL ICD optimizes bus data transfers in order to reduce peak saturation of the bus, much like the new DirectX pipeline. 

Parallelized Memory Access

Detonator 4 Software’s new OpenGL ICD is more efficient at helping the GPU and CPU access memory in parallel.  This allows each processor to cache data before it is transferred between system and graphics memory, increasing performance in high resolution antialiasing modes.

Vertex Programs

Vertex programs have been optimized in Detonator 4 Software, yielding performance gains in some applications, and even larger gains in heavily vertex-processing bound applications.  Examples of applications that utilize these features are SPECViewperf, Pro/E, and NVIDIA’s Chameleon demo.

The end result seems to be more efficient usage of memory bandwidth in both OpenGL and Direct3D applications.  The one thing that caught our eyes was the “Parallelized Memory Access” which seemed to be best suited for the parallel memory access that would occur between the CPU and the integrated GPU on a nForce motherboard. 

Another major feature of the new detonator release is improved performance under Windows XP.  For those of you that have had experience with Windows XP you’ll know that the animations and effects can slow down normal OS interaction tremendously.  While we’re still working on XP benchmarks to measure the effectiveness of the new Detonator 4 drivers under Windows XP we can say that the new drivers definitely feel faster under Windows XP.  We’ll provide more performance analysis on that later this week.

    Good old GeForce 2 and Quake. So many good memories. I played it instead of doing my homework. I just order it at, I just wanted have fun. Reply

    Thank you for sharing this set of drivers for Nvidia. I think if you are the owner of such a video card, you need to regularly update the drivers in order to get the maximum performance for your video card. Nvidia is an American technology company that develops graphics processing units and systems-on-a-chip (SoC). The company's developments have spread to the video games, professional visualization, high-performance computing and automotive industries, where Nvidia's on-board computers are used as the basis for self-driving cars. The company was founded in 1993. In 2018, it was the world's largest manufacturer of PC-compatible discrete graphics with a share of 81.2%. I learned this information from YouTube videos in which nvidia developers talk about their company and show production capacities. I found more than a dozen videos on this topic there and noticed that most often such videos had about 26 thousand views! I am sure this is because their authors have resorted to using the services of in order to wind up views. Reply

    If I know so much about nvidia I would create instagram profile about it. I know where to get followers for instagram profile. You can read it too from this site Reply
