intel has big leg up here and hopefully they won't drop the ball increasing there HD graphics with next/newer chips .
For this, I think Intel will increase the gaming performance for GPU too, even Intel is not one of the HSA member.
(but I am not sure about compute, as it look like this is just for saving bandwidth to improve GPU performance only.)
Because it is strangely that Intel support 1 thing to improve the GPU performance with Haswell, which is one thing for HSA.
The second extension, InstantAccess is simply Intel's implementation of zero copy. Although Intel's processor graphics have supported unified memory for a while (CPU + GPU share the same physical memory), the two processors don't get direct access to each others memory space. Instead, if the GPU needs to work on something the CPU has in memory, it needs to make its own copy of it first. The copy process is time consuming and wasteful. As we march towards true heterogeneous computing, we need ways of allowing both processors to work on the same data in memory. With InstantAccess, Intel's graphics driver can deliver a pointer to a location in GPU memory that the CPU can then access directly. The CPU can work on that GPU address without a copy and then release it back to the GPU. AMD introduced support for something similar back with Llano.http://www.anandtech.com/show/6863/intels-pixelsync-instantaccess-two-new-directx-extensions-for-haswell
So I think that HSA can be future, but the issues is the standard for HSA, and Intel don't agree standard set by AMD I guess?
And even HSA making GPGPU more easy, but it increase more issues for devs, so they need to learn about how to using GPGPU too, and also transfer of data, as the latency between CPU and GPU is still there, they just reduced.
Back to Topic, I got a small patch, but it look like even it is small patch, but it can be important.
(without restart, so don't worry about after installed this update you need to restart your computer)

A little tips here.
If you see TiWorker.exe is running and biting CPU+Hard Disk usage, it is just compress unused file that get replaced/patched and keeping the old file by Windows Update.
If you don't like that, you can just remove the old file that get updated by Windows Update, but remember!
After you deleted the old file, you can never uninstall the Update, as the old file is not there, Windows update can't get the old file, then replace the new file.
So except you really lack of disk space, and it is stable after update/you like to reinstall windows than uninstall update, then it is not recommend that remove the old file.
