Just tried again and same here have not been able to view the ORBX forums since 9th of April 1900GMT from the UK. This is all I get... Fatal error: Class IPS\Login\_Steam contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (IPS\Login\_LoginAbstract::canProcess) in /home/orbxcom/public_html/forum/system/Login/Steam.php on line 277

I came across this, looks like REX looked into and they thought the FPS hit was too much but that was before the DX10 fixer. Hmm I wonder if its now more feasible in DX10 mode? http://www.realenvironmentxtreme.com/forums/index.php?/topic/13555-cloud-shadows/

Hello Steve or any other knowledgeable persons, I am wondering how DX10 mode changes the way FSX processes graphics. 1) My Understanding was that in DX10 mode the majority of FSX graphics go direct to the GPU and it takes some of the pressure off the CPU, but the CPU is still doing FSX work. 2) Does FSX with DX10 Fixer benefit form SLI or Crossfire and if yes by how much? Regards, Sebastian

Hi Wulf, thanks for the info. I am glad its not just me. I have been busy with real life and have not had any time test any further. But I think my test seemed to show turing effects slider down a bit in FSX might help the situation. Seb

Itneresting Matthias, that information is helpful. I need to find some time for more testing but I think we are slowly narrowing the cause and a solution. Seb

I think its got to do with the level of Anisotropic filtering. But will not have time for testing for a week or so. I will get back to it later and report back. No Rush at all Steve. Thank you for your time.

Hi Steve, I may have solved my issue, by change settings back and forth testing something suddenly changed. I now get at worst a 10FPS drop so I am getting 30 to 20 FPS. Under very heavy forest fire and smoke views I some times the graphics break down to flashing triangles, but if I drop special effects slider from High to Medium normal graphics are restored. This is the contents of my FSX effects.cfg in "fsx/Effects" folder, is this what you are asking for I hope(this is with my effects set to high). ; These particle spite limits are applied based ; on the "Special Effect Detail" settings slider. [sprite Limit] Medium=5000 High=9999999999 Low=1000 ; These particle emit rate modifiers are applied based ; on the "Special Effect Detail" settings slider. [Emit Rate] Medium=0.700000 High=1.000000 Low=0.300000 ; If an emitter has its LOD flag set and the viewpoint is ; further away than this at the time the effect is started ; then the emitter will be disabled. [Detail] Forced Distance=250 ; The [Emitter Detail Distance] and [Emitter Detail Modifier] ; tables work together. If an emitter is further away than a ; distance specified in the distance table then the rate it ; emits particles at is scaled by the factor specified in the ; modifier table.

Steve here a couple more shots. 1st I turned on engine fire failure and I went from 30FPS to 16 and the lower screen grab I go to 4FPS when I pan the view to get the smoke to fill the screen. I have Rex soft cloud and when I fly through clouds I do not have the issue, its just with smoke and spray.

My monitor is standard HD 24inch 1920 x 1080. I agree Steve its a puzzle, something local to my PC. I doubt my GPU GTX680 has any issue. From what you have said I am starting to think it could be a GPU setting some where or a line in my FSX CFG file. Fsx dx9 and dx10 are equally affected. This is one of the test I made. As soon as the smoke is in view I go from 30 to 6 FPS or lower.

Hi Steve, I tried no AA and there was no FPS drop, tried 2X and 2XSGSSAA there was a slight but acceptable FPS drop from 30 to 25ish. At 8xCSAA and 4xSGAA FPS drops to 3 or 2 and the my screen turns into triangles, the GPU or CPU just cant cope. I used a extreme test, flying a default mooney bravo and forrest fires from Orbx KWYS scenery. the fires produce a large amount of smoke. I am going to try 4x and 4xSGAA.

I will try X4SGSSAA(again), 2XSGSSAA and None AA and see what happens and report back. Thanks for your time with this Steve as its not really a DX10 issue because it happens in DX9. Steve could it be simply that the smoke affect in FSX is very old and not written for modern GPU's.

No Demo but there is a freeware version I tried it but the payware version a million times better. I can not recommend it it enough. REX 4 Direct textures and soft clouds work perfectly with it. You have to set DX10 mode in the REX4 DT options(look in the lower left there are three items) I love the cockpit shadows they make it a lot imersive and the shadows disappear when you fly into cloud. At night you can control the reflections of the starts and moon on water, you can control all reflection on water day and night to make things look a lot more realistic. DX10 fixer does a lot. read through the manual and you will see what I mean. To get the best out of it you need to read the manual a lot. I revisit it all the time and keep improving the look and smoothness all the time. bets of luck.

I have 8x supersampling, I had tried 4x supersampling. I have not tried NO AA setting because even if it works the flightsim would not look good at all. I will have to try to avoid smoke and spray coming in the cockpit. I was trying to find a fix but I doubt there is one.

Hi John, The "8bit textures should always be left off" according to the manual, its a option for testing something or other I read it recently. Seb
