You can use the FPS Limiter to get smooth gameplay out of the areas that give you high FPS (although with the BPools and Highfixme tweaks I just leave my fps unloacked and no limiter, works fine).As far as the shimmering, I'm not sure. I used a 5870 at one point, but gave up on it because it sucked handling any amount of autogen well.

I've got almost exactly the same kit as you except for a 4850 and I can only get 3.8Ghz on my i5 750. In Catalyst control centre I'm currently using AA and AF as application preference, and other sliders on quality, i.e one click in from the right. This page explains the settings quite well : http://forums.guru3d.com/showthread.php?t=96948.I reckon you should back off your autogen density and scenery complexity to normal or dense. You'll get used to it!What has helped is adding the tweaks mentioned by Bojote on this forum. My framerate is the same but it's a lot smoother. I deleted my FSX.cfg and let it build a new one and added the following:[bufferPools]UsePools=0 [GRAPHICS]HIGHMEMFIX=1 and this one...[GRAPHICS]ForceFullScreenVSync=1Oh, and this...[JOBSCHEDULER]AffinityMask=14Run the framerate locked at 30fps... that's smooth, 22fps jittered which I think is related to the refresh rate of 60Hz now that Vsync is finally working but 30 is fine. I could see no difference between using the FSX frame lock or the external one. I prefer FSX's as I run 2 monitors. I get the odd slight hesitation but I think my 4850 is really struggling to keep up. I may have to sell one of my kids to fund a new Graphics card. Please read Bojote's stickied post.. He knows what he's talking about, I don't.. BTW Thanks Bojote!!!Don't hesitate to ask if you want to clarify anything.

Thanks guys. I guess if I turned the autogen off completely then that would be one way to stop the shimmering!The only way I can get things to look good is to use supersampling AA but the performance then drops to unusable levels.I normally leave the FSX FPS setting to unlimited but have tried the FPS_Limiter tool too. Despite all the tweaks I couldn't really find anything that was perfectly smooth. Sometimes it is fine looking out the front but as soon as I look out the side windows everything seems pretty unsmooth.Will have a play with those fixes again and see what happens.Would there be any tweaks specific to my scenery addons that would help things or does the fsx.cfg settings not matter if running FS Genesis, UTX and REX?Thanks

hi ringoa good start to understandinng ccc settings is here:-http://www.tweakguides.com/ATICAT_7.htmlHave tried external frame limiter but had problems with computer clock time out and some crashes, so went back to internal set at 20( can increase this if I reduce LOD to 3.5)my ccc settings are:-Smoothvision HD Anti-aliasing .....tickedSmoothvision HD Anisotropic Filtering...tickedcatalyst A.I. ......unticked (advanced)mipmap detail Level.... High Qualitywait for Vertical refresh........always onAdaptive-aliasing ..........untickedhave TEXTURE_BANDWIDTH_MULT=80 TextureMaxLoad=12 ( not to sure if this is doing anythink as I have now using PoolSize[GRAPHICS]STALE_BUFFER_THRESHOLD=10 // Try 10 as well.. but 1024 should give you a perfect smooth experience when using vsync ON ForceFullScreenVSync=1ForceWindowedVSync=1HIGHMEMFIX=1at the moment have gone back to PoolSize=8000000 I testing using default cessnar in PNW and no stutters, occasional pause only ( still trying to resolve this..maybe disk access)

Do you have a MipBias setting in your fsx.cfg, that caused horrible shimmering for me, taking out the command made things looks 100% better.

Thanks - will have a look into that. I would say that tweaking CCC settings would be good to fine tune gameplay but the shimmering issues seem a lot harder to get rid of.

Definitely not. I tried adding one a while back and it make things x1000 times worse!

Downloaded now. What exactly is it and what does it do?

In the Graphics tab I use Filtering...'Anisotropic' with the Anti-aliasing unticked.you can try ticking this option, it stops the shimmering for me, but the downside on my mid range rig its kills the frame rates.of course you need to tick 'use application settings' in ccc

Hi Ringo,I have been simming forever and could not tell you how many systems I have bought over the years. What I have learned is that the biggest gain overall of without a doubt will bet the investment in hardware. FSX just sucks up CPU power like a black hole. There are many cfg tweaks that can help for smoothness, and the GPU drivers and settings for the the quality of the display certainly play a part, but the one investment that will make the biggest difference is the hardware and the proper tuning of that hardware. I too have tried many tweaks and done this very systematically. What many have found including myself, is that one tweak will work for someone, but not someone else, at least in comparison to effectiveness. BP, Vsync, HighmenFix (*******'s findings), seem so far to offer the best return in my experimentation for the latest cfg tweaks which have come out lately. Others such as TML, Affinity etc have also offered up some improvement in certain areas of the sim . Again, the hardware will be your best investment overall. Some have said, well we already know that so why post the obvious. There was a guy the other day that posted that he saw no improvement in the cfg entry Fiber_Frame_Fraction (dont have my cfg open but you may know this tweak), to help with blurries, when he set the entry at .10 or .99. This is proof to me that the reason he saw no difference with those settings is that his system was sooooo fast, that the settings did not matter. He was running the latest 6 core processor and a really high end GPU. I dont remember his drives but I am sure he either had an SSD or a very effecient hard drive or two.A good system may be cost prohibitive for you, but until you can afford to do this, you may end up tweaking and not flying. This is my opinion and their are many that would agree with what I say. There will also be those that disagree, and that your hardware is good enough.It sounds to me that you want more with FSX and are not finding that with the approach you are taking now. Search the threads and see what you find and try to make a sound decision.The only other thing you can do is turn down the sliders. For me, I want to turn the sliders up, and there is only one answer to that!!!RegardsBob G

Thanks guys. I have been improving performance with some of the tweaks but still have quite bad shimmering of the autogen trees. When I run REX my fps almost half although I can get a constant 30 in most cases. Maybe it will just take a little more fiddling around.

I hate to keep harping back to the wonderful 'Flightzone 01 Portland' scenery but the developers proved that FS9 wasn't done. Blades of grass and moving traffic was present without any loss in fps.I know that this isn't prevalent to FSX but illustrates what can be done with a workable sim.Vauchez wrote and re-wrote the polygons for this package and by perfecting it showed that a fluidsim with great scenery can be done.Why oh why, can't someone produce a sim that doesn't require new hardware at great expense, to run. Vauchez did this and last heard was working on the failed 'Airliner XP'.It's a shame that these people are lost, we would all benefit by their professionalism.

It sounds to me like extremely dense default autogen is what slows FSX down. I use high resolution photographic scenery and terrain mesh (Horizon VFR Generation X Version 2; England and Wales), detailed airports (VFR Airfields and Xtreme series by Gary Summons), and no default autogen*, and I get acceptable framerates running FSX at 1280x1024 resolution with maximum detail levels (apart from Water, which is set to the medium 2x setting) using my 2.83Ghz Q9550/4GB PC2-8500 RAM/512MB GeForce 9800GT powered system.* Custom autogen appears to be a different story, because I can run Earth Simulations' Alderney and Isles of Scilly with the autogen set to Extremely Dense (and the texture resolution set to 15cm), and I still get decent framerates (even with the Flight1 Cessna Citation Mustang)!

Is there anything I can do to the autogen to make it look better? Is there such a thing as replacement autogen? I run FS Genesis, UTX and REX so maybe I don't even need autogen?

Hi Ringo, I have never owned an ATI board, and not really sure if Nvidia offers up better IQ than your ATI. You could search the forums to see. I had sent you a post above about hardware, and I mentioned that you may have to turn down the autogen in order to get FSX to a point that you are satisfied. Again, there has been considerable emphasis on tweaking, and some of the tweaks have been a tremendous help to some but not for others. Go over to the addon specific forums (UTX, REX) and see what advice they may have, you may find something there that may be of help.RegardsBob G
