We’ve not yet thoroughly tested under DX10, and Phil Taylor has made clear that the DX10 “preview” is not necessarily backward compatable. We restricted ourselves in Vancouver+ and Victoria+ to only using FS9 compilations when we needed a function not available in FSX, such as seasonal tree textures. These problems can arise when an “alpha” channel is used for transparency or semi-transparency. There are also some backward compatibility issues in DX9 which affect third party aircraft and scenery compiled using FS9 tools. Note that these tests all had bloom disabled. So for those who want the eye candy, they may see a slight improvement. I found an increase of about 11% in frame rates with high autogen and water settings, and a decrease of about the same with those settings set low. Now the thrust of the product is the amazing array of new missions and some cool new aircraft, but some work has been done on performance optimization. I ran my framerate benchmark on XPack today.
