Hello!I have downloaded the new driver version 7.1 for Radeon X850 series. After installing it and tweaking all my Catalyst settings back to where I had em before, I have a problem: most things on the screen look blurry :(In FS9, especially, the outside views make it clear that the 3D acceleration works, although there are now rougher edges on objects. But inside the cockpit all guages look very blurry.Tried to tweak and play around with display settings in Catalyst and in FS9 but nothing helps. Should I roll back to previous driver? Any thoughts? I have Acer AL1917 19 inch monitor.Assistance will be gratly appreciated.Thanx!

I have a 9800 Pro and have had better luck with Omega drivers. They have been more stable. Otherwise, roll back to a driver that works.

My advice too. Roll back, review, check, and research more before trying again.JS

Did you uninstal the previous driver fully and properly to begin with? It is important to do that with ATI--nVidia cards tend to be less fussy about that procedure. I have an X850 XT PE and an nVidia 7900 GTO and have worked with both.You might need to check settings inside your FS9.cfg file as well to check that it reflects the correct resolution among other things if you choose to try again; and also to make sure that you do not have duplicate settings for your video card because this can interfere considerably with normal operations.Roll back in the meantime and start again.JS

JS, thanks.Sorry for lameness, but by duplicate settings you mean same in Catalyst as well as in FS9? For e.g. setting trilinear filter in catalyst and in FS9 would be a duplicate setting? Should I just set those in catalyst and skip in the FS9?With previous driver I would just set everything to max in catalyst and in FS9 with correct screen resoultion and all worked well.

By duplicate I means make sure that under DISPLAY in your fs9.cfg file, you do not have more than a single entry reflecting your video card and the resolution of that card. If you have more than one entry, the results can be devastating to the performance of fs9. When I recently swapped video cards from ATI to nVidia, I had duplicate entries in DISPLAY and it crippled by frames. When I realized this and edited the card, frames and fluidity doubled.JS

I dont know about the new 7.1 Cat drivers, but I tried the ones before, the 6.12's and they gave me bad problems in FSX, I actually went back to 6.9's for best performance and stability in FSX on a similar card to yours.

I removed an ATI X600 and replaced it with an ATI X850 XT PE, and have the latest X850 Catalyst/drivers. I made no changes to the cfg. after installing the new card. Looking at this post string I took a look at my FS9.cfg. I show two different video card references within cfg. First one is (shows old card):[sOUND]SOUND=1SOUND_FADER1=0.500000SOUND_FADER2=0.100000SOUND_FADER3=0.300000SOUND_FADER4=0.800000SOUND_FADER5=0.500000SOUND_FADER6=0.800000SOUND_QUALITY=2[DISPLAY.Device.RADEON X600 256MB HyperMemory.0]Mode=1280x1024x32TriLinear=1[DISPLAY]UPPER_FRAMERATE_LIMIT=30TEXTURE_BANDWIDTH_MULT=40and then further down in cfg.(shows new card) :[FlightPlanMap]SHOW_AIRPORTS=1SHOW_VORS=1SHOW_NDBS=1SHOW_APPROACHES=1SHOW_INTERSECTIONS=1SHOW_VICTOR=0SHOW_JET=0SHOW_AIRSPACE=1SHOW_FLIGHTPLAN=1SHOW_WEATHERSTATIONS=0SHOW_WEATHERSYSTEMS=0SHOW_DATATAGS=1SHOW_TERRAIN=1show_waypoints=1show_airways=1show_markers=1show_volume_boundaries=1show_ac_twr=1[DISPLAY.Device.RADEON X850 Series.0]Mode=1280x1024x32TriLinear=1[JOYSTICK_SLEW {EC8EEC10-99ED-11DB-8001-444553540000}]AXIS_EVENT_02=AXIS_SLEW_HEADING_SETSo my new X850 is not shown under [DISPLAY}but lower down in cfg.Do I need to do something about this? If so, what do I specifically edit in cfg.? Thx. for the help.

The noted display video card did not show up in the post. Here's correction.I removed an ATI X600 and replaced it with an ATI X850 XT PE, and have the latest X850 Catalyst/drivers. I made no changes to the cfg. after installing the new card. Looking at this post string I took a look at my FS9.cfg. I show two different video card references within FS9.cfg. First one (my old/removed card) shows up below the SOUND section as:SOUND_QUALITY=2(DISPLAY.Device.RADEON X600 256MB HyperMemory.0)Mode=1280x1024x32TriLinear=1(DISPLAY)UPPER_FRAMERATE_LIMIT=30TEXTURE_BANDWIDTH_MULT=40and then further down in cfg. second one (new installed card) shows up below the (FlightPlanMap)section as: show_ac_twr=1(DISPLAY.Device.RADEON X850 Series.0)Mode=1280x1024x32TriLinear=1Do I need to do something about this? If so, what do I specifically edit in cfg.? Thx. for the help.

If you have just one single video card in your FS9 PC, then your FS9.cfg file should reflect a single entry for that one card. If the entry for your old video card remains inside the cfg file, you must delete that manually so that the sole remaining entry is for your new Radeon 850 card. Typically, the .cfg entries are for (a) DISPLAY device and (b)mode (i.e. resolution, e.g., 1280x1024x32, etc.). This is what I have listed in my .cfg file on my old FS9 PC when I had a Ti4600 card:[DISPLAY.Device.NVIDIA GeForce4 Ti 4600.0]Mode=1600x1200x32TriLinear=1You might also try going to Bilinear rather than Trilinear filtering. You can change the filtering setting from within the sim itself, inside the DISPLAY pages, I think under the "Hardware" tab. Filtering can have a weird impact for some PCs. I changed mine from Trilinear to Bilinear and it fixed a bizarre display anomaly with 2D and 3D cockpits and views.JS

JS,Thx much for the help. One final clarification-does it matter where the new video card (X850) description lines within the .cfg file reside, i.e. does it have to follow the SOUND_QUALITY=2 line?I assume when I am done deleting the old card lines and closing up the gaps that the only thing I need to have when complete (for the new card) should be (assuming I do have to have it after the SOUND_QUALITY=2 line) is:SOUND_FADER6=0.800000SOUND_QUALITY=2(DISPLAY.Device.RADEON X850 Series.0)Mode=1280x1024x32TriLinear=1[DISPLAY]UPPER_FRAMERATE_LIMIT=30TEXTURE_BANDWIDTH_MULT=40[TERRAIN]If I mess up the cfg. file, how do I get the default back?Thx. again.

It need not necessarily reside in that specific location. As far as I am aware and based on my own experience, you can rearrange cfg file entries as you wish, make spaces, etc. and it should still work.Normally, you would make a copy of your cfg file before editing just in case you screw it all up but even if you do not and things go wrong, I believe FS automatically "rebuilds" a cfg file when you run FS the next time round.JS

JSDid what you said and it made a great improvement in FS9 fluidity, smoothness, and frame rates as well as greatly improving Active Sky, and the (already great) experience of using the 767 LVLD for all of my flight sim flying. And thanks also to others on this post string who brought this issue up. Appreciate the help!

Hooray! And Well Done ! Great to hear that.Yeah, for some reason, those small video card entries in the cfg file make a massive difference in fluidity. I don't know why. Funny, isn't it? Just a few characters of typed print and your sim is restored to a brilliant hobby.Enjoy it.JS

Hey JS (or any others)Referring to my past post on this issue, I recently went back into my FS config file and looked around, and low and behold the ATI 650 card description was back in there, and all of the other changes I had made to the config files per FS Tweaks recommendations from others were also no longer there. It seemed my config file somehow got revised back to what looks like the original FS default values, and what it was before I made the changes you recommended. What may have happened, and how do I get any changes I made to FS config. (including all FS config tweaks) to stay there permanently? BTW, I did save the FS config changes after making them. BTW, should one change the FS config with the recommended tweaks if using Ground Environoment Pro? Do the recommended tweaks compliment GEP and the graphics are better with both, or in any way do the tweaks screw up the graphics when also using GEP? Does it make any difference if using FS9 or FSX when making config changes that will "stay permanent" or any effects with also using GEP?Thx. and appreciate the help.
