Okay - I've looked around for this but I just don't know how to describe this problem effectively. Texture "flickering" isn't quite the word I'm looking for, as when I Google this, I get a completely different issue.I'll just describe it. Sometimes, when using FSX in DX10 mode (and more rarely, but it DOES happen, in DX9 as well), textures don't load correctly. In their place, I get either a placeholder texture or an FSX splash screen - not sure quite how to describe it. This happens much more frequently when using third party addon planes, and three in particular; Thomas Ruth's Airbus A300, his Airbus A330, and Captain Sim's 757 Captain (all DX10 compliant planes, I'm sure you know). This issue affects not just the aircraft, but most noticeably the ground textures. This issue does resolve itself, but when panning the view, the textures flicker in and out as the textures load and unload from memory.For anyone still lost, I've included a screenshot while using the CS 757. Also note the affected AI planes in the top right corner. I'm thinking this could be an issue with the way I have my fsx.cfg configured.....Can anyone help out a fellow simmer?(inb4 "use DX9." nah I'm good. If I wanted that, I'd have stuck to FS9.)And the all important: my system specs.CPU: AMD Phenom 2 X6 1055T (2.8GHz x 6 cores)Motherboard: Gigabyte GA-890FXA-UD7RAM: 4Gb 1366MHz DDR3 (possibly a problem?)GPU: XFX Radeon HD5770 1Gb model (latest drivers and CCC installed)OS: Windows Vista Ultimate x64 sp2 (I'll be honest, not my smartest decision. Looking at 7 x64 within a few months.)FS version: FSX + Acceleration + all the service packs.

I don't see a screenshot. For textures to be rendered properly in FSX with DX10 Preview enabled, all textures must be DX10 compatible. So, any textures FS9 or earlier will not render properly with DX10 Preview enabled. Some of the AI aircraft in an AI addon may still have DX9 textures. If FSX cannot find a texture to render, it will substitute it with the FSX Splash Screen. Sorry I can't help you any further. My biggest complaint with DX10 is the shimmering on some taxiways but that can be fixed by changing the textures to cement instead of asphalt (or so I understand). I have not tried it myself as I prefer to fly in DX9 (until DX10 programming is fixed).Best regards,Jim

Gah. I posted the file, but when I posted the topic, I got a "driver error" issue, and when trying to access the topic to edit...same thing. So, trying from another computer - though it's pretty much what you described.What clues me into the fact that it's not a missing texture issue is that this error does not occur with any other aircraft in DX10 mode, and only seems to occur in dense scenery areas (even places like London. Forget KSEA, where that screenshot was taken). That's why I think it might be something to do with fsx.cfg....and if it is, what parameter is it I need to change for the texture loading?Edited: Reread the above post and thought I'd also chip in I'm not using any AI, scenery or weather addons. Pretty much stock FSX+Acceleration with only aircraft addons.

DX10 Preview mode in FSX is flawed. My advice would be not to touch it with a barge pole.

Well....First, I did say if I wanted DX9 I'd have stayed with FS9. Second; I have been using DX10 Preview mode since I got my Phenom system together - around June 2010, and never seen this issue until I started to use the CS 757 and Tom Ruth's Airbuses. It's only starting to rear its head with those aircraft. I've narrowed it down to texture load; which is why I'm asking what parameter I need to change in fsx.cfg to tweak that out.Edit: "if I wanted DX9 I'd have stayed with FSX". fixed. was typing too fast.
