Absolutely not true(actually the opposite is the legend, that amd/ati have better image quality than nvidia). There is nothing wrong with image quality under directx 9 games on amd cards. Actually the api has nothing to do with image quality.
Really, I suggest you take a good look around in various forums, I'll be happy to give you links. AMD/ATI lost there edge in image quality a long time ago, I've been watching it happen since the day's of the 9700Pro.
I don't run very many DirectX 9 sims/games anymore but OpenRails, TS2013 and few older racing sims and flight sims I run all without a doubt look better on Nvidia. Again just take a look in any flight sim or racing sim forum. UKTrainsim as well as Trainsim.com (justed 2 weeks ago actually) have had plenty of discussion about poor image quality with RailWorks/TS2013 (another DirectX 9 game) and ATI/AMD.
How about the latest bugs in AMD Catalyst drivers that prevent you from forcing super-sampling AA and v-sync on OpenRails, is that completely wrong also?

Outerra is a nice techdemo, but if i set the tree quantity higher, the same happens as in or, or ts2013, or arma or every open world engine... as the draw calls reaching one cpu core limit in render thread, fps starts to fall... Opengl is faster of course, that's not a surprise as directx is meant as another vendor lock in technique from microsoft...
Have you run the Outerra demo? If so on what hardware because I haven't seen any major performance hit with all those trees on the three different setups I've been running Outerra on over the last two years.
As far as the Outerra/TS2013 comparison goes, well obviously they can't be compared because just like what we've seen with other DirectX 9 game engines it's primarily CPU dependent and is a totally different animal compared to Outerra.
