Difference between HD4850 and 4870 please

Yup, saw that link, gave it a quick peruse but will look in depth later, I have to be honest I abhor back ground services and hunt them down with a passion , good to know you can turn some of them off though.

The new CCC does not do all that stuff...However it does have some background stuff running.....

Look at the link three posts up and their guide will tell you whats running and how to kill it if you want...


That being said the new 9.3 driver is good for me... (no difference than the 8.12 as I can tell)

Uninstall your old one from Add / Remove...Then run Reg Cleaner...

That should do it......:wave: :ernae:

Well it arrived, installed ok, used the offical CP drivers from Radeon to eliminate the Catalyst control center, still only 18 back ground services running so all good there, now the bad news, not a lot different in FSx LOL, you have to laugh, a modern 1GB GPU little better than a two year old 256MB GPU.

There are some small gains, I can move autogen up a notch ( dense ), fluffy clouds ( which never seemed to have much drain here anyway ) at full distance, water at 2x, might try higher later, and overall a little more stable in tight turns, less stutters and flashing / spikes etc.

If I drop AG to sparse then its liquid smooth, bufferpool is 75,000,000 and TBM seems to make no difference between 10, 40 or 70, at 100 it drops FSx like a lead ballon and really messes with the GPU, so much that a full power on off is required to reset it.

There was a tweak from Phils blog wherethe default value was 0.33, cant seem to find that anywhere now, anyone remember what it was ?, its not affinity mask or job scheduler as far as I can recall.

Hi Michael...No CCC installed? How do you set up the stuff then like Vert sync and AA and AF ? Or monitor your fan speeds or See the card temps?

Anyhow..here is what you are after...


[SIZE=-1]To reduce the blurries, Microsoft has reworked how Flight Simulator X scheduler prioritizes background tasks in FSX. Now much more CPU time is devoted to loading scenery data, including terrain textures, at the expense of somewhat lower frame rates. In my opinion, this change has mostly solved this cause of the blurries, although the scenery loader can still get behind at extremely low frame rates (less than 10 fps) or at very large airspeeds (faster than 600 knots).[/SIZE] Th[SIZE=-1]ere are several ways to adjust how much CPU time FS devotes to loading scenery and textures. The easiest way is to set the target frame rate slider to a value that your machine can consistently achieve. The lower you set the slider, the more CPU time is diverted from rendering to loading data. Another thing you can do is to modify the following variable in FSX.CFG:[/SIZE]


[SIZE=-1]FIBER_FRAME_TIME_FRACTION=n[/SIZE]

[SIZE=-1][ [/SIZE][SIZE=-1]n = [/SIZE][SIZE=-1]0.01 - 0.99 ][/SIZE]

[SIZE=-1]This variable determines the amount of CPU time given to loading scenery data as a fraction of the time spent rendering. For example, the default value of 0.33 means that for every 3 milliseconds spent rendering, FS will give 1 millisecond to the scenery loader. If necessary, you can use a larger value to devote more time to loading (any number between 0.01 and 0.99). Or, if you don't have a problem with the blurries and you want slightly higher frame rates, then you can use a smaller value.[/SIZE]

[SIZE=-1]Should you choose to use this "tweak", here's how to do it:[/SIZE] [SIZE=-1]Insert a line directly under the [MAIN] section and enter[/SIZE]


[SIZE=-1]FIBER_FRAME_TIME_FRACTION=0.33[/SIZE]

[SIZE=-1]Experiment with the number entered here and adjust them to your taste for a balance of quality & speed. It has been reported that for true photo scenery depending on your PC specifications, you may need to set this value as high as
[/SIZE]0.50 or even 0.66[SIZE=-1].[/SIZE]

[SIZE=+1]* * * For Dual Core Users * * *[/SIZE]

[SIZE=-1]I have found that a setting of 0.01 - 0.20 will allow you to have your Autogen set to "Very Dense" and maintain a Frame rates of 20 - 100 FPS rate (depending on your area of flight - FPS will be higher in rural areas and lower in large cities). [/SIZE]

I use ATI tray to set up the GPU and for GPU temp I use HWMonitor, but I'm sure those features are in ATI Tray somewhere, basically everything in CCC but with out the system overheads of CCC. I have ATI set to not run on boot but run when I click the icon, I do have two appications of ati2evxx.exe running which I dont think I should so I'm looking into stopping them as well, I think that link above mentioned them somewhere.

Thanks for the cfg edit, thats the one ! .
