Direct Link to SpeedGrade disables GPU in CC2014.2

Question

Bug as noted in the other thread, but ... refined and clarified. Working in a Direct Link process, I cannot do anything whatever to the simplest sequence in Sg without an immediate notice that "There are insufficient Video Resources" and Sg is disabling GPU acceleration. This is, again, after it was using less than 3% of the GPU and only around 278Mb of vRAM. It then runs slow as molasses.
If I just try to keep working, the time lag between clicking anything and response of the program continually slows ... starts at a couple seconds of lag, soon gets to 30 seconds between my action and its reaction. Totally unusable.
I can restart and re-enable GPU ... but it will just keep doing the same thing.
The only thing that gets me semi-back in operation is to simply go to the Pref's panel, re-set to "Use GPU accel" but WITHOUT re-starting. It will run semi so-so ... far faster than if I don't do this and simply try to keep working (as noted above) BUT ... definitely slower than it did on CC, or CC2014, through any of their minor builds.
I've run CC Cleaner and wiped both PrPro & Sg ... downloaded fresh & re-installed. Exactly the same behavior.

I posted this earlier in a the creative cloud forum with no responses.  I'll post it here to see what you guys think about it:
I'm not too familiar with the forums at this point, although I have been using them for a few months to receive some great information.  However, I've got some good ideas, and perhaps you'll think of them as good ideas too.
From what I understand, at the moment, there's no way to tell what problems may exist in any updated versions of the Adobe CC software.  For example, when recently updating to the newest version of Adobe SpeedGrade, I and many other people are having many troubles getting it to use the GPU.  Because of this, it is assumed to be a software issue that we all just have to deal with.  For the majority of us, uninstalling this version, removing ALL of its remnants (which can be important when using SSDs) and re-installing to the previous, working version can be a huge hassle, especially when the permission of an administrator (such as for those who do this for a living in the workplace) is required to do so.  This is what I have to say:
At the moment, is there any way to know (by personal experience, not what Adobe claims to have fixed and updated) what problems and other changes may exist in the updated software without scouring each forum's posts for each CC application?If not, I propose creating a collective area in which people can list differences they've noticed throughout the newest version of the software and problems they may have experienced with it.
So by this point, you're probably considering why anybody should do this.  Here are the reasons that I think that this would be a huge benefit to everybody:
People, in advance, could look at the collective experiences of those daring enough to update to the newer versions.  This would help because:
Now they can decide, for themselves, whether or not to update (rather than find out the hard way since no information regarding software bugs about the newer versions were made easily available).
Remember, not all of us have an easy time uninstalling and re-installing things when parts of the new program no longer work. If there was one forum, or area, or whatever it takes, where people could post all of their experiences with any of the newest versions of the Adobe CC software, I feel that it would be a huge benefit to all of us.  Of course, people would have to be daring in the first place to try the newest software and then return to post about it, but for those of us who are not fortunate enough to do so, this would greatly help.  See, I'm stuck doing horrible color grading with SpeedGrade despite having two GTX 970s in this machine and am unable to turn back to a previous version (at least, it would make more sense for me to wait until a newer version of all the software comes out considering my employer).
Let me know what you guys think about this idea, who I should talk to in order to make it a reality, or (most importantly) if an area on these forums already exists and I'm completely unaware of it.
