These are my drivers (Latest version) as I'm aware
May I ask how you uninstall your old drivers and install the new ones? Do you use the AMD Cleanup utility?
http://support.amd.com/en-us/kb-article ... ility.aspx Also i find it's worth going into the %appdata% click the "up" arrow next to the search box and remove (delete) the AMD folder in the "local low" and local files. EMPTY your re-cycle bin (trashcan) then reboot now check the device manager (right click) Windows icon and make sure the graphics card is no longer showing up in the device manager. At this point it's worth seaching the web to see if you have the latest Intel graphics driver as I suspect your machine like mine has two cards an Intel and AMD if these are out of date download and install the Intel drivers, re-boot your machine. It is very important that both graphics cards are running up to date drivers! Now your machine has rebooted install your up to date AMD drivers RE-BOOT again. I also find I get better FPS by using Game Fire to shut down a lot of unwanted and resorce hogging stuff that runs in the back ground it can be found here
https://www.smartpcutilities.com/gamefire.html I can gain another 5 FPS by using this utility. In answer to your question about my FPS, It can vary, on the ground at EGKK (Which is highly built up) I will get 15-22 FPS up in the air in the cockpit it will be 18-25 FPS. Be aware it is very dependant on the plane you are flying as well. My FPS results are with the Boeing 777 which is a well known resorce hog, If I fly say a Cessna I can get another 20-25 FPS on top of the 777 results, Also all the variants within the shaders, AI, weather, ETC will also affect the results drastically. Get back to me if you require any other help Clive
