Make GPU features work on Win64
Project Member Reported by jsc...@chromium.org, Aug 5 2013 Back to list
Sorry for the overly broad title. The issues I'm aware of are:
 * GPU initialization fails on Win64 where the same system succeeds on Win32
 * HTML5 and Flash video performance is much slower than Win32
 * What 64-bit DLLs should we be shipping for DirectX (we're supporting only Win7+)?

To build x64 you'll need to use ninja, and set target_arch=x64 in your GYP_DEFINES. If you want an optimized or official build you'll need VS 2012, because the 2010 optimizer has major code-gen bugs for x64 targets. You also need to use the Release_x64 or Debug_x64 directories in ninja, because we have too many weird dependencies that prevent you from using the normal Release and Debug.

Fix Win64 DirectX redistributables

Adds a gyp variable to simplify WINSDK path strings,
and grabs the x64 files rather than x86.

And it turns out that I just didn't know what DirectX DLLs were needed. Looks fixed now.
