hardware-acceleration

问题 I have tried to disable 3D acceleration on my machine that operation system is Windows 7. I opened the DirectX Diagnostic Tool but DirectX Features can not be changed: In addition I also tried to change Troubleshoot settings. However, it also can't be changed: How can i disable directX featrues? Note: My directX version is 11. 回答1: If you mean for your own application, you can disable GPU hardware acceleration by opting for the WARP driver type ( D3D_DRIVER_TYPE_WARP ) when creating the

问题 I have an algorithm and I've been trying to accelerate it using OpenCL on my nVidia. It has to process a large amount of data (let's say 100k to milions), where for each one datum: a matrix (on the device) has to be updated first (using the datum and two vectors); and only after the whole matrix has been updated, the two vectors (also on the device) are updated using the same datum. So, my host code looks something like this for (int i = 0; i < milions; i++) { clSetKernelArg(kernel

问题 I'm working on a minisite that features a lot of jQuery animation. It works fine in Safari, Chrome & IE9, but the animation is really choppy in Firefox (7, 8 & 9) on OSX. I thought CSS animation would be smoother, so I adapted the iPad version of the site and tried that out in Firefox. It seems just as bad. I haven't spent a lot of time with Firefox, so I'm not sure what I'm doing wrong here. Do I need to trigger GPU acceleration (like using translateZ(0) in Webkit,) or is it just used all

问题 These days, I need to draw many images on a canvas. The canvas size is 800x600px, and I have many images of 256x256px(some is smaller) to draw on it, these small images will compose a complete image on the canvas. I have two ways to implement this. First, if I use canvas 2D context, that is context = canvas.getContext('2d') , then I can just use context.drawimage() method to put every image on the proper location of the canvas. Another way, I use WebGL to draw these images on the canvas. On
