Low 2d Direct 2d score with GTX 970/4790k

[NoelC]

Hi, I'm having a recent issue that is affecting my Direct 2D score with passmark on my GTX 970.

It seems every single test I am running, from CPU to Hard drive, is right where it should be EXCEPT the Direct 2D test (The one with the spinning arrows and such).

I used to get between 30 and 50 fps on the first few tests I ran after installing my 970.

Here's where it gets weird:
I haven't ran any tests in a month or so, so last night I decided to test again for fun. I noticed that the Direct 2D portion ran much slower, between 11 and 18 fps. And also the arrows stayed fuzzy during the zoom in and took a while to render them sharper.

I have been wondering about this EXACT SAME problem since November of last year.

I believe a Windows 8.1 Update destroyed Direct2D performance.

As I have an ATI card, it's clear it's not related to specific display drivers or even to the brand of graphics card.

I do Passmark benchmarking regularly - I have for years - in order to spot problems or trends, so I can pinpoint exactly when this slowdown happened. Note the screen grab below.

The only place it gets a little odd for me: After a Windows Update in Mid February, performance of the Direct 2D benchmark seem to mostly return, but then it went back to dismal levels after the very next update.

Try updating to the current 347.09

In the beginnings, there were a lot of issues due to various driver bugs.
Some of them were insane bottlenecks, so this should actually improve!

Do you still remember which driver you used for the card back then?
The additional updates from Windows could also be the culprit, they are affecting GDI redering a lot afaik.

Good article from 2010 describing the issues:

Yeah, It was about 2 revisions ago. So 344.11 I believe was what I was using. I dont really want to roll back drivers though.

Also I'm using Windows 8.1 x64

I ran this test several times and noticed that about one out of every 5 tests would behave like it used to, between 30 and 50 fps, but the rest were between 11 and 18, which is slower than Intel HD 4000. Not good.

SO I tried playing with a few settings like power options and checking my cpu speed on CPU-Z to make sure it was running at full clock speed, which it was. Check temps, those are super good (I have a very good cooling system for my PC). My CPU and GPU are not overclocked, I just have XMP profiles turned on for my RAM so the timings are at factory settings and all CPU cores run at the same frequency of 4.4Ghz under the windows high performance setting.

I can't figure out what's going on. Was there a recent windows update that affects this kind of thing? Are the new nvidia drivers for the 970 the problem? Any one else experiencing this phenomena?

Thanks in advance for any and all feedback.
