[英]Does the Pixel Bender with Flash would use the GPU?
I write a Pixel Bender kernal for my flash. 我为Flash编写了Pixel Bender内核。
I know that the pbk would run in another thread. 我知道pbk将在另一个线程中运行。
But when I run my swf, the GPU usage shows 0%. 但是,当我运行swf时,GPU使用率显示为0%。
I want to know does the Pixel Bender with Flash would use the GPU. 我想知道带Flash的Pixel Bender是否会使用GPU。
Adobe say this about the GPU in Flash Player 10.1: Adobe对Flash Player 10.1中的GPU这么说:
"The desktop player still uses software rendering for this release." “桌面播放器仍在此版本中使用软件渲染。”

It's a little old, but I believe it still to be true. 它有些旧,但我相信它仍然是真实的。
As Joony says, PixelBender does not (currently, 2010) use the GPU. 正如Joony所说,PixelBender(目前是2010年)没有使用GPU。 But it does run multi-threaded, not just in a different thread. 但是它确实运行多线程,而不仅仅是在不同的线程中运行。 On a multi-core machine (almost all, nowadays) this is still a big performance boost if you need to do a lot of independent computation. 在多核机器上(如今几乎是所有机器),如果您需要执行大量独立计算,这仍然可以极大地提高性能。 ActionScript can only (currently, 2010) run on one thread, while PixelBender can use lots. ActionScript只能(当前,2010年)在一个线程上运行,而PixelBender可以使用很多线程。
March 2011 update: the new Flash Player 11 (Molehill) APIs are GPU accelerated. 2011年3月更新:新的Flash Player 11(Molehill)API加速了GPU。 You can use PixelBender3D [1] in combination with the Program3D class [2] to get GPU acceleration with a software fall-back for incompatible machines. 您可以将PixelBender3D [1]与Program3D类[2]结合使用,以通过不兼容机器的软件后备来获得GPU加速。
Notes: PixelBender3D is an update of PixelBender. 注意:PixelBender3D是PixelBender的更新。 Also, this will only work with FP11 and not FP10. 此外,这仅适用于FP11,不适用于FP10。
