I'm not familiar with that particular card, but ATI/AMD has optimizations in the drivers to help make things look good in some games.  Unfortunately, those slow the heck out of FSX.  Go into the catalyst settings and start with changing the settings from quality to performance.  You should be able to save a profile for FSX that retains those settings for FSX.

fsx do not recommend ATI cards

OK guys i got my new Radeon 7770 today, upgraded from a XFX 9500GT. However when I try fsx in the PMDG 737 I get same FPS, (15-19) in VC and the same problem that prompted me to buy a new gfx card, long waiting time for the ground textures too sharpen (blurry for about 10 seconds, till the textures are sharp, GEX). All in all there is absolutely no difference between the 9500GT and 7770. I also deleted the CFG (Bojote) and the same issue. Am I doing something wrong? Do I have to reinstall FSX?

 

Thanks

Sorry but most of the "ATI is not recommended" is not accurate anymore. ATI has been more than fine since the 6000 series was released a few years ago. Current drivers have dealt with any old issues from back in the day. Its now just old news passed on from person to person.

 

So instead of bashing a $129 ATI card (HAHAHAHA) lets try to support this problem you are having. What is the rest of your system? What airport are you using with the PMDG 737. That plane and FSX are CPU heavy. You might be asking your system to do too much.

 

Can you please indicate the following details...

 

CPU TYPE and SPEED = I see it now. Phenom II X6 @ 2.7 (a bit slower than a stock i7 920)

RAM = I see now 8

Video = equivalent of a GTX650

 

Settings on the Graphics Tab in FSX?

The aircraft, scenery and weather tab?

What about the Traffic tab?

What airport is that PMDG sitting at?

 

***EDIT - I see by your profile now... Phenom X6 1045T @ 2.7Ghz That's kind of low for FSX with a plane like the PMDG. How does the system do with the default Cessna 172SP?

 

As for the video card, what you bought was the equivalent to a GTX650. Sub $140 card. Don't expect miracles from either nVidia or ATI from that range but they should work ok with modest settings. But this might help you. Although Super Sample AA will be too hard on that card. Stick with MSAA.

Actually I uninstalled all amd and nvidia related items from add/remove programs, boot with safe mode, ran driver sweeper, remove the ati and nvidia extras that remained there, and then when the computer restarted, it always rebooted by itself in the starting windows screen. What went wrong? I had to do startup repair and restore for the system to come back on

 

This is an ugly situation. A restore point? Ouch. That can sometimes make matters worse but you had to by the sounds of it.. What is your device manager looking like after all this? 

 

Another thing I believe when switching brands from ATI to nVidia to ATI again in FSX is I have heard that flushing the shader cache in FSX is required. Even when going between DX10 and DX9. Here is a god guide for that. Basically you are deleting the contents of your Shader Cache folder and letting it rebuild.

If I was sitting there trying to fix your system, this is what I would do. Once you are CERTAIN you have all of the motherboard and video drivers properly installed and no anomalies in the device manager, I would...

 

#1. Set FSX back to DX9 if not already. Exit FSX.

#2. Delete FSX.CFG (copy a back up to your desktop if you are unsure)

#3. Delete contents of the Shader Cache per the guide (flushing the cache)

#4. Start up FSX and let all that rebuilt.

#5. Just set modest settings in the SCENERY TAB for now. Like the DEFAULT Medium.

 

Test a basic default FSX airport with the default 172SP. How did that go? Load up the PMDG NGX and try the same. How did that go?
