Figured I'd give Prepar3D a second shot after going back to a Triple Monitor setup. Was curious how it handled it.. Not well at all. 5 minutes departing out of SeaTac with the Lancair Prepar3D CTD with a OMM error.. FSX handles all this without issue and flew from SeaTac to Concrete just dandy. Matter of fact I've never (touch wood) had a OMM error before with FSX so I'm rather surprised to see Prepar3D collapse so easily.

 

I saw one person on the Prepar3D forum was having an issue with this also.. Anyone here getting OMM errors?

I have had that but intend to try under 64bit os to see what happens. I normally see 1.8gb usage but have also seen scenes creep to over 2gb. Other sims also have similar issues. Very sporadic. I begin to wonder id Window7 may have an issue...

Haven't tried it yet.....

I am on Win 64.. I know P3D is large address aware just like FSX is.. I want to play this sim but I just can't trust it. G3D crashes, OMM crashes.. It's like FSX Pre service packs and FSUIPC caputuring G3D faults all over again. Which is why I just now started simming as a hobby `full time' since all that stuff with FSX is finally managed. I don't bother really reporting any bugs to them because you're SOL for support as soon as you put a single addon into the game.

Well trying to "play" this sim is your first mistake ;) jk... I haven't had any of these issues yet, I run under Win7 x64, what size textures are you using?

Taking into account that Prepar3d is not a 100% carbon copy of FSX, something may go wrong with virtually any addon which you use. So, If I were you, I would try to enable add-ons in Prepar3d one by one in order to determine which specific one causes the issue.

 

For me, Prepar3d worked fine under both Win 7 x64 and Win XP 32 bit configurations, although for the latter case I had to add /3GB /userva switches and disable one of my video cards in order to give system enough of address space.

Hi,

 

I'm running P3D with Windows 7 (64 bit), I have three Samsung T260HD monitors running at a resolution of 5760x1200x32 with no problems.
