I saved both of those pictures and compared them in Photoshop. I do see a difference, but it is in the color of the shadow, not in the actual thickness of the font.
Since you didn't add a shadow, I have to assume that it is caused by the "Fit" setting of the Program Monitor. Try it again with the image set at 100% instead.
You are right - there are no shadow at all.
I do not change the program monitor size.
With 100 percent - the same issue.
Just type something and change mercury engine settings and You will see difference.
OK. I have duplicated the problem.
I suppose the question is "why is this happening?". The exports from both settings are identical, and are the same as the preview that uses the Mercury hardware (CUDA) acceleration. Therefore, the previews for the Mercury acceleration are OK but the software only option is faulty in some way. I will have to leave this for someone more experienced with the Mercury Engine. But there is a problem that can probably be fixed eventually. I hope.
I suppose it has something to do with the way that Premiere Pro renders previews. I tried using the highest quality previews I could but there is still a difference.
If we can get an Adobe Engineer to reply, then I will skip the Bug Report if they provide a sufficiently good reason, or change in settings. Otherwise, this is a bug that needs to be fixed as far as I can tell.
Todd? Kevin? Bueller? Bueller?
I did my test with text over sand. Here are my test files:
This first one is a screen capture of a small area of the title over sand. Mercury Engine is using hardware.
This second one is a screen capture while the Mercury Engine is set to use software only.
If you put them both in Photoshop or Fireworks and switch back and forth between the tabs you can easily see the difference..
It is only the preview that is a problem. The exports both look like the first one, with and without hardware in use. It is just the preview when using software only that is a problem.
OK, now you have me confused Jim.
I have no idea what you mean.
Black letters have to have something under them or there will just be a black frame.
Edit: Or are you saying the background has to be white (no black)?
Well, most titles are white, and the habit is to put a black clip underneath it in the sequence. Titles seem to work fine over video with GPU on, but they get weird when you put that black (or other matte) clip under them.
The OP has something under the title in his sequence. I'm saying get rid of that, and the problem should go away.
I put mine on sand. That is pretty neutral. Samples indicate
R153 G153 B102 and R153 G102 B102. Those hover around the middle and seem fairly bland to me. I don't have much in the way of black under mine and I see the problem.
I have proven that the export is fine, but the preview is very misleading. I can see where it would cause a problem with titles that had to be specifically placed in an exact position.
Try it for yourself. If you can find a way to preview a standard font the same way both with and without the Mercury hardware acceleration, please explain your steps.
I used these settings for my test. It is one of my new standard presets for obvious reasons.
Edit: I tried it with a 480p preset and it was WORSE!
I have proven that the export is fine
Mine came out with the error, which was how I first noticed the issue. Watching a title that started over video and then continued over black, I could see a very noticeably shift in thickness once the title hit the black clip underneath.
Try this experiment. Add a normal title over a black clip, just like we've been doing for years. With GPU acceleration on, turn off and on that black clip with the track eyeball. You'll see the title change thickness.

I think your issue and the one we are addressing here are different. It is only a matter of the preview. I can see where what you describe can be a problem, but that would be due to bleed through of the black through the less opaque portions of the font. In this case, I have no black. The difference shown in Bill's example is from making changes to the Mercury engine between hardware and software only.
One of three. I use 24p for scripted video (or semi scripted anyway).
I use 60p for some video I shoot, and if quality is the main issue, I stick to all I-Frame using 30p.
The Software mode is the intended look.
Then you'll need to run in that mode. GPU processing does things differently. You're seeing that difference.
"CUDA-accelerated processing is done in a linear color space (i.e., gamma = 1.0) at 32 bits per channel (bpc), which results in more realistic results, finer gradations in color, and better results for midtones."
Having identical issue on the Mac side, 100% reproduced. Basic font over rolling video. Font is significantly thinner with cuda acceleration on, and correct with cuda off. Basic logos in Titler appear to be affected as well. Must be problems with alpha + cuda. Has anyone filled out a ticket, or has any Adobe rep acknowledged this? It's a pretty big issue.

Edit: I keep thinking that this would be easier if we just got on a conference call. You know?
Sorry I am late to this conversation. While I don't know precisely what's happening here, I would suspect it has to do with GPU processing in linear color. In Premiere Pro CC, we have a new feature that will help problems like this. In Sequence Settings, you can enable "Composite in Linear Color." See the screenshot below:
In Sequence Settings, you can enable "Composite in Linear Color."
The new feature is actually the ability to disable it. Currently with GPU acceleration on, you have no choice but to use Linear Color. With Premiere Pro CC users can turn that part of it off, while leaving GPU acceleration as a whole turned on.
With Premiere Pro CC users can turn that part of it off...
I just love having choices. Fix or no fix, it doesn't matter if I can change it to the way I want it.
I am looking forward to Premiere Pro CC
Out of curiosity, in CS6 is there any scenario in which font and/or logos created in the titler, placed directly over a video clip in a sequence appears correctly when Cuda acceleration is enabled?
I'm trying to figure out if there is any workaround, or if I'm dead in the water to edit the basics in Premiere with hardware acceleration enabled.
I believe that Kevin already provided the answer that there is a fix, or at least a workaround, in Premiere Pro CC. So starting on June 17th, you should be good to go. Assuming you subscribe.
I don't see any way to fix this in CS6 since they don't intend to upgrade CS6 once the new software is available (with some exceptions).
But it is certainly worth asking him again, just in case.
I don't believe this would be an upgrade to CS6, it would be a repair. Apparently, it has never worked properly.
There should be a patch to fix CS6, if it is in fact this linear color issue. I think it's a bit outrageous that you can't create a font only name super in Premiere's CG with hardware acceleration turned on. We're only talking about the basics here.
