Hi,I am new to Vista 64 and am in process of OC, so I have not had alot of time to do any testing with the DX10 Preview as of yet.I was curious as to how many of us here are using DX10 and what are your experiences and thoughts. Had you used it and went back to dx9, or did you decide not to use it and for what reasons?RegardsBob G

I tried it once and chose to stick with DX9, hence my best system is running XP x64.Many addon aircraft are not able to work with it properly (particularly those that were originally designed for FS2004), and many textures, most noticeably the runways and some buildings, flicker very much.

Yes, the flickering seems to be the most prominent complaint. To bad. On the positive side, some had mentioned improvement in smoothness and FPS increase but not much detail. Thanks for your inputBob G

I switch back and forth between DX10 & 9. I use DX10 more, but as the previous posters said, there is some flicking on the default scenery runways. I do not get this with addon airports, only default airport runways. Also runway lights do not work with DX10, most night lighting does, but not the runway and taxi way lights at most airports. I alway use DX9 for night flying. However, DX10 is noticably smoother for the most part, but not so much so that its worth using. I think most poeple use DX9 more. Its a shame they were never able to get these issues resolved with DX10, because I do like it better, but the issues mentioned, Kill it.

i7920@ 3.6G - VistaFor me the smoothness of dx10 is not worth the downsides. So i use Dx9.AS for smoothness, i now use the fps limiter tool, which you can find links to if you search fsx forum on this site. The tool only helps high end systems.

It seems DX10 is not used by most. Yes, I had been following most of the limiter threads here and there. I did download it and sun java, but will wait until I get my box leveled out.Bob

I also switch between DX9 and DX10. Since a week or two I am using DX10 when I fly VFR, mainly with the RealAir Scout. When I fly VFR I like reflections in the water, lots of autogen, etc. DX10 runs a lot better on my system than DX9 with all these settings enabled! It does have some problems (mentioned by others) but to me the gain in fps is worth it. I used to have problems with microstutters when using DX10, but these are (almost) gone with my new system.When I fly the MD-11 (high and dry) I use DX9, mainly because FSAA is better with DX9 because then I can use nHancer, which won't work with DX10. And the MD-11 VC really needs good FSAA, so that's why... For VFR DX10 FSAA is good enough but not for the MD-11. This means I have to turn down autogen a lot, traffic too, no water reflections, etc. but since I fly high and dry this is no problem for me. I do have to add though that also with DX10 fps is a lot less with the MD-11. It USED to be okay, but now I've gotten used to great fps with DX10 using the Scout, the fps with the MD-11 sometimes sinks too low for my taste. It's still workable though, somwhere between 15 to 20 during landing.BTW I switch by using two fsx.cfg's named FSX.cfgdx9 and FSX.cfgdx10. Whenever I want to use one, I simply rename it to FSX.cfg. This way I do not have to startup FSX, switch to a different mode and restart FSX again (which is mandatory when switching between DX9 and DX10). I also don't have to load the different settings I use for the two modes because they are all saved in the fsx.cfg.

Well thank you for you time. I just moved from xp 32 to Vista 64 and just getting used to Vista. I have done no optimizing yet, as I am going through a very careful OC project for my computer. After I get it stable, I will first try to optimize the OS, then experiment with other FSX options, including the new optimizer which seems to be sweeping the flight sim community. I will as part of this certainly try the DX10 stuff. We will see. I thank you again for your detailed reply. Take CareBob G

Using DX9 and DX10 aswell. DX10 runs faster but IMO because it overrules all driver AA settings and uses the standard FSX AA which isn't very nice, but nice to the Graphics Card.Setting DX9 to the same setting (I think its 2X2 or 4xS, not sure) gave me comparable framerates to DX10.

I think it is to each person's taste.Also if your running XP, one cannot run DX10 preview.I use DX10 all the time, but I have the system to take advanatge of it.Dell XPS 730 Extreme Quad core 9650 3.00 , O/C to 3.94gb ramNvidia GTX 285Vista 32bitI've noticed in Windows 7 Beta ( I have a duel boot on my system) that the DX version is DX 11, what that means for Flight sim, who knows, as with what hapepned with Aces earlier in the year, I've not heard of any certain plans to make the next version. I guess time will tell, Yes I agree there is a lot of add ons one cannot use with DX10, but there is more and more every month being released.Phil

The only reason why i bother to taxi and not just spawn on runway is cause fsx progressive taxi makes it easy enough to be worth my while.Since progressive taxi does not work in DX10, it was a no brainer for me to drop back to Dx9. Plus some runway lights dont work in dx10, but that is no big deal, like struglling to find your runway in big airport.Dx10 = no progrssive taxi = dx9

Yes no progessive taxi is a issue with DX10, although it does show from top down view. I still kind of think it is a driver issue why it won't show from other views.Not that I use it much, as I can folow ATC most times, as I do have real life flying training. VFR day and night PPL licence in real life.Note sure what you mean by runway lites, they come up okay on my system under DX10Phil

I just switched to DX10 recently and I am loving it. Everything has a good contrast now, light bloom does not hurt your FPS as much, and there are nice cockpit shadows! The AA also seems a lot better in DX10 than DX9. The only problem I am having with DX10 is the flickering taxiways, but i haven't tried progressive taxi yet...

I use DX9, since I use nHancer.Plus, the water in DX10 looks completely fake, you get near tropical seas in non-tropical areas.And the bleedthrough taxiways always annoyed me.

My performance utilizing DX10 is a little better, but the lower level of FSAA somewhat ruins the experience for me. The better performance comes at the price of jaggies. DX9 + 8xFSAA looks a heck of a lot better, IMO, and the performance difference is not that noticable. If you want bloom, you could always download the END Series plug-in and use that with DX9.

ATI 4850 512Mb with the latest drivers, win7, 3Gb Ram.DX10 on gives an unstable FSX with some flickering; DX9c looks okay. Performance is almost the same wth both.RegardsBert

Also runway lights do not work with DX10, most night lighting does, but not the runway and taxi way lights at most airports. I alway use DX9 for night flying.
That's very strange. I fly nothing but DX10, one of the reasons being lighting (including runway/taxi lights) look alot better. The night environment rendered by DX10 is far superior to the DX9 one IMHO. Maybe there's something wrong with your configuration?As for the flickering taxiways, they occur in stock airports as well as addon ones and seem to be related to the "asphalt" texture (I guess some addon airports use the default textures). Replacing the asphalt taxiways with concrete ones solves that problem. That's certainly not a solution unless you love fiddling with ADE, or if you fly to/from a handful of airports but it highlights it's really a limited problem. I'm gonna experiment some more and see if it can be solved but my hopes are not very high I'll succeed.
Plus, the water in DX10 looks completely fake, you get near tropical seas in non-tropical areas.
I haven't seen this, probably because we don't fly in the same region. Could you please point me to where this happens? I would like to have a look at that.Cheers/Jonas

I had to switch to DX10 to maintain frame rates after getting Triple Head 2 Go, and so far it's been great, I don't have the flickering runway problems after switching to nvidia's latest Beta Drivers 186.08. Progressive taxi is gone, but I never used it anyway.I wish the AA was better, but a few jaggies for double the frame-rates is worth it. I also have an SLI set-up which I think it takes advantage of(according to Nick N).I had to change up some scenery, Aerosoft's London is a NO GO, and some planes don't show up at all.It's a mixed bag but the benefits outweigh the flaws for me.

Try flying east from KDLH. I live there and the water does not look like that on DX10 mode....I run 2xlow or medium with dx9, maybe 1x high on dx10 would look different, not sure, never tried

I just use the Airport Design Editor ("ADE"). It's free, very potent and fairly easy to use. Iterating through all airports to change all taxiways like this it is another matter. Also, I would prefer to have asphalt taxiways where there should be asphalt taxiways so this "fix" is not something I'm happy with. Possibly I could experiment with replacing the texture itself. If it's true that some addon airports doesn't see this issue that could actually help. Unfortunately I'm not a very talented texture artist ... (<-- hint :( )/Jonas

I run 2xMedium in DX10 and I think water looks very good (although not different in any way I can see when compared to DX9). My only problem is injerting good looking wave animations/reflections. My oceans looks like a mirror right now. I've tried REXand that "WaterConfigurator" thingy to no avail. Anyway, I fly up to Lake Superior and have a look at the tropical waters up there./Jonas

Thank you Jonas, I am trying FDE right nowFor me Dx10 is a winner. I don't care about fps but FSX is much smoother and I really appreciate cockpit shadows and waves.

I was using DX10 because it gave me cockpit shadows and allowed me to turn on Bloom and max out the water detail setting without turning the sim into a slide show.However, after I discovered the FSX HDR mod, I've gone back to DX9. I still need to keep the water one notch from max, but the sim runs much better than it did maxed out under DX10, with no display errors. Also I can use all the great planes that were not designed for DX10, and the water isn't a cartoon-ish blue any more.
