Whenever you edit your settings in FSX, the LOD_Radius and Texture_Max_Load settings will revert to the default.  You'll have to open up the configs and manually change them to the higher numbers.  If you edit just the fsx.cfg, this will not happen.  DX10 or DirectX 10 provides better graphics than the older DX9.  There's probably not too much difference between them as far as graphic quality but DX10 performs better than DX9.  DX10 is definitely not causing your OOM's.  High FSX/display driver settings cause OOM's and it has been proven by at least one computer expert (Word Not Allowed) that high settings will cause OOM's.  Your computer just cannot handle all of the calls and functions to run FSX when settings are set to the max. 

 

I have been using DX10 since the day Steve provided the shader fix.  I have MegaSceneryEarth V2 scenery for the Eastern USA and have been flying over those states.  I recently set my LOD_Radius to 7.5 and my Texture_Max_Load to 4096 and ran a flight from KORD to KSTL.  Great FPS except around FSDT KORD and Taxi2Gate KSTL.  Still the fps were smooth and I had no problems.  Great eye-candy!  Then I decided to do the same flight with AS2012 and turned on the weather for the flight.  Totally impossible!  The fps were constantly in the single digits.  I think REX is the similar.   So you will need fsx settings for flying with no weather (yet there will be some nice HD clouds); the other with REX loaded and running real weather.  The latter will require that you dramatically turn down your FSX settings.

Okay, so I'm going to stay with DX10 for now. I just went into REX and set the 3D clouds to 2048x2048 (down from 4096 setting) and re-loaded all of the textures. So at least with the real weather, the clouds should be a bit lower in resolution. I always change settings by editing the fsx.cfg AFTER any changes in FSX itself. I also try to use nVidia Inspector to manage things like Anisotropic and AA, and I guess everyone has to find that sweet spot to get everything working just right.

 

I'll try the same flight with and without REX and see what happens now. Is there any real advantage to reducing the display resolution in FSX itself? I'm running at the max for my monitor - 1920x1080 - but I could drop it back a notch if that would help. Problem is with this stuff is that we want our cake and eat it, too. I don't care too much for AI trafic, but I love the scenery and the real weather.

Hi Gary,

 

The problem people run into (me included) is setting the 3d clouds to HD (2048 or 4096) in REX or AS2012.  That might be okay if you leave Texture_Max_Load at 1024 (the default) but, if you move the TML to 4096 too, you will crash or your fps will shoot into the single digits and this will especially happen if there is severe weather.   

 

There are some good tweaks for the FSX.cfg and there are some really bad tweaks.  I try to stay away from them other than I do like the TML set at 4096.  This means you don't have to go HD in your addons like REX and AS2012 as it is already set in the FSX.cfg.  I think you will still have problems with the 2048 3d clouds (and if your TML is set at 4096).

 

DX10 and DX9 are basically the same except FSX set up a special folder within FSX for a limited version of DX10.  You should be able to switch between DX9 and DX10 on the fly without making any changes whatsoever to your NI or FSX.cfg.  People want to tweak it more as DX10 shows the sun shadows inside the VC and sometimes those shadows have jagged edges.  That doesn't happen in DX9 as DX9 does not have that capability so people think DX9 is superior.  It's not.  DX10 is the same as DX9 with a few minor changes to graphics (like shadows and white cap oceans, lakes and rivers depending on the weather).

 

Best regards,

Thanks for the input, Jim. I have gone into REX and set the 3D textures to 1024, and left the fsx.cfg TMLset to 4096. Stupid question, but if TML is set to 1024 and the 3D textures are set to 4096, what trumps what? I set the TML to 4096 after two separate suggestions - one from a repainter who said that his current model was done in HD mode and to get the best "look" the TML had to be set at 4096 - and the other when I got REX and they also said to increase the TML to 4096 for the best textures.

 

It gets a bit confusing, doesn't it? I'm beginning to think that the best bet is to go with thew low-res 1024 and enjoy the flight instead of trying to get the most realistic views from the cockpit. I guess there's a happy medium there somewhere. In my own opinion, I want realistic weather first, and if the clouds don't look like very real clouds, well, that's okay.

It probably depends.  If you want to have 1024 as the TML in your FSX.cfg and 4096 in your REX settings, that's okay.  Just not both.  I installed HD clouds with AS2012 but reduced the settings in AS2012 to 1024 and 512 and have the TML set to 4096 and I still get HD clouds.  The problem with the 4096 setting for Texture_Max_Load in your FSX.cfg is that it sometimes does not remain at 4096 and, if you change a fsx setting within FSX, the setting will go back to the default of 1024.  In REX, that won't happen.

 

Like I said somewhere, I rather fly without real weather than suffer the agonies I might get with low FPS if I have the settings all placed at the highest.

Well, it just crashed on me again. This time I was about 400 miles into my flight, smooth weather, running REX weather and Radar Contact. This time I had just opened a couple of windows - one for the EFIS and another one for the pilot's controls to adjust the range, and everything just stopped. No OOM crash, just a lock-up. I heard somewhere that opening multiple windows can do this, so maybe...

 

In any case, I am now dropping back to TML of 1024 and setting my REX back to 4096. I just can't figure out why I cannot get one good flight out of this thing. I flew the MD-80 from KSFB to KFLL, a short hop, with no problems. Wonder how far I can fly before I hit that wall. Geez!
