By the way, can you write an answer (%systemdrive%\$Windows.~BT\Sources*.log) as the question only seeks to narrow the scope. If you don’t it’ll wait some mounths.
You don't need to wait for GF1000: there are plenty of other cards currently available which support Direct3D, some quite inexpensive. Since you're replacing integrated graphics, performance should not be a primary concern.
@AFH : geforce 1000 would feature a great performance improvement due to the particular swtich to Pascal. This is the occasion to acquire the same performance for far cheaper.
OK. I have been around long enough to avoid the first release of any new product: first customers most often turn out to be gamma testers (not just computers, I use the same criterion for everything, from cars to televisions to washing machines).
I am not sure I gave you an answer, only suggestions of things to try. You know best the details of what worked for you, so it's probably better to submit the answer yourself (an acknowledgment would be nice). Glad to have been of help.
