Please guys, if you feel some sympathy for the project, I beg you not to keep spreading this misinformation.
The picture with 5000+ gpus is perfect. The so called blurriness is a bilinear filter that's applied by default to interlaced modes to reduce flicker. It doesn't affect progressive modes. Ironically I've been adding bilinear filtering to interlaced modes in GM since the first day. Now it's done by default by the gpu.
By comparison, pre-HD5000 cards are a real pain to deal with in W7: they require GM to run in admin mode, interlaced modes run at halved refresh, they can't cope with super resolutions really well, lots of monitor detection issues that suck.. A lot of crap that's infinitely worse than an innocent filter on interlaced modes.
Now looking behind, i believe that if I had focused since the beginnig on adding support to HD 5000+ cards instead of legacy ones on W7, the transition to W7 would have been easier.
By the way, prefer the 6450 to the 5450. Although it has a single analog output, it handles super resolutions better.

Ha Ha, that's the reason why I have never experienced such picture degradation. Thanks for the clarification. Hope we will see no gossip anymore on that subject.

You know you're going to need to elaborate on that? ;D

I found it easier/cheaper to just get a slower current/newer gen card..
I got an R5 230 (brand new with warranty).. works a treat and cost the same as the old cards

Well in my experience the HD 5450 that I've tried (Asus 1 GB) has a problem with "high" vertical super resolutions (e.g. 2560x480): it will show a black frame from time to time making the picture flash. On the other hand my HD 6450 (Asus too) is 100% solid on this regard.
The issue is easily avoidable anyway, by simply not using "high" vertical super resolutions. Indeed, my current setups just use a few progressive super resolutions, and additionally some standard 4:3 interlaced modes, e.g.:
2560x240
2560x248
2560x256
640x480
664x496
688x512
"High" vertical super resolutions are overkill anyway unless you have a serious GPU. The idea here is that the GPU should be able to process all scaling required within the vblank period, so you don't get tearing when using "manual" vsync (frame delay).
