Hi, today am going to show to fix EA FIFA 15 LAG AND INCREASE FPS.
1. Firstly, you will need RADEON PRO app you can get it from www.radeonpro.info
2. After installing it run the program, once the program is running you then pin it to your taskbar for easy access.
3. In the program you will see a green plus icon at the top, click on it to add a new profile. Find your FIFA 15.exe in its relevant folder.
4. Select the TWEAKS tab over on the right hand side and change the VSYNC CONTROL drop down to always on. Change the DISPLAY REFRESH RATE value to 60hz. Check the TRIPLE BUFFERING box too.
5. Then check the DYNAMIC FRAMERATE box and put 60 in as the value. Press return to make sure it sticks (you can check with the value at the bottom) if it doesn't work, try unchecking the DYNAMIC FRAMERATE box and selecting LOCK FRAME RATE UP TO MONITORS REFRESH RATE instead. I have found success with both option.
6. After that enable FORCE HIGH PROCESS PRIORITY under TWEAKS and FORCE TRIPLE - BUFFERING (OpenGL) under ADVANCED tab to give the best results, right click on the EA SPORTS FIFA 15 profile you just created and then click apply now after that minimise the app.
7. Then go to documents in your pc and enter FIFA 15 folder open the fifasetup then change it to these:
AUDIO_MIX_MODE = 0
CONTROLLER_DEFAULT = 0
DISABLE_WINDAERO = 0
FULLSCREEN = 0
MSAA_LEVEL = 0
RENDERINGQUALITY = 0
RESOLUTIONHEIGHT = 720
RESOLUTIONWIDTH = 1280
VOICECHAT = 0
WAITFORVSYNC = 0
then save it.
8. In FIFA 15's launcher option make sure that NO LIMIT ON FPS is selected and don't tamper with the rest option.
9. Go to search and type PERFORMANCE then click ADJUST APPEARANCE PERFORMANCE OF WINDOWS, select CUSTOM then make sure only SHOW THUMBNAILS INSTEAD OF ICONS and SMOOTH EDGES OF SCREEN FONTS are ticked then click apply. Turning off your internet also increase your FPS.
10. Before launching the game always ensure you have selected and applied the FIFA 15 profile you created in the radeonpro app.
