My experiences after 3 weeks DX10 testing:

 

 

Patch: shader DX10 V3.1 easily to be installed "plug and play". A must have.

 

Performance:

Not easy to get the FSX.cfg individually optimized, but thanks to the

outstanding staff-forum contribution I got it ..... ~20% better FPS vs. FS9.

There is no mandatory need for FSX.cfg tweaks, but a lack of visual and FPS

performance will be the consequence.

NV inspector is the key, otherwise partially flickering e.g. taxiways was not managable.

No more desktop crashes.

 

Visual impression:

Scenery shadows and brightness are more realistic.

Default clouds are ok and "borderlines" of adjacent cloud layers are smoother.

 

Compatibilty to sceneries:

FSX default day and night/night-lights are ok.

ORBX US westcoast sceneries are good, only street night light flickering remains and

to be hopefully solved.

My few Aerosoft GA sceneries are only DX9 compatible, therefore not enjoyable in DX10.

 

Compatibility to aircraft:

The FSX default B737 and Learjet are fine, not checked other FSX default aircrafts.

Freeware A320/A319 is impressive, see e.g. AVSIM file library pa320fd_v3_302581.zip.

 

Further suggestions to the gurus:

To include into the how-to-doc a) addon scenery and B) aircraft compatibility issues

more detailed and clustered. This will be a growing list or table, for sure,

as it will reflect the simmers´ experiences too.

 

 

Due to the overall scenery improvement I´ll stay with DX10, when flying

in FSX default or ORBX sceneries. I will only switch to DX9, if the sceneries

are "significant" not DX10-compatible.

BTW, I made a shortcut to my desktop from .../AppData/Roaming/Microsoft/FSX

to ease swapping DX9 to DX10 in the FSX.cfg (D3D10=0 or 1).

Way ta go, Wulf! A nice precis of DX10's operation. You took the time and trouble to investigate and it's paid off. It's the same experience I and may others have had since Steve introduced his early patch to forums. It's still on-going - his latest work is into water colour, FSWCLite, and runway night textures.

in NA ORBX sceneries occasionally "flying houses in autogen area" are recognized in DX9 mode. This has been commented in the ORBX forums as an unrepairable FSX-bug. I never recognized this anomaly in DX10 mode again.
