Hey Guys...
Many of you might have this problem of stuttering or lag while playing.....well we really can't expect everyone to have the latest in computer hardware. So I have decided to post a method by which you can remove or at least reduce the lag problem. It is a combination of two methods that I have read:
Method 1: ( by Rinaldo )
Launch FIFA. The most effective action is to change the priority of the process running FIFA. Start the Task Manager by pressing Ctrl-Alt-Del. Then, using the Task Manager select the process fifa.exe and, clicking the right mouse button, select priority and choose the value “high”. Now the game should work better.
Unfortunately every time you start FIFA again the priority returns “Normal” and you should repeat the operation… but there is a very useful free program http://www.prnwatch.com/prio.html that allows to save the priority that you want to assign to a process so you have to do the job only once and it will do the job for you every time you will start FIFA again. I definitely recommend to try it.
There are other actions that you can do for improving the performance, I tried them and I obtained some improvements but they were not enough until I changed the priority of fifa.exe. But maybe they can be enough for you so I will report them here so you can try yourself.
In fifasetup.ini be sure to have:
RENDERINGQUALITY = 0
This has the main effect to keep the rendering frequency at 30Hz, otherwise the game tries to achieve the 60Hz when it has enough computational power. In my opinion 30Hz is a very acceptable frame rate (consider that the phisyologic limit of human eye is 25 Hz ). Doing this, you limit the CPU load drained by the rendering task and it helps.
You can then create a rna.ini text file in the Game subfolder and add the following lines:
[]
// Threads priorities
GAME_THREAD_PRIORITY = 0 // original was 0
RENDER_THREAD_PRIORITY = 1 // original was 0
INPUT_THREAD_PRIORITY = 2 // original was 2
AUDIO_THREAD_PRIORITY = 3 // original was 2
FE_THREAD_PRIORITY = 3 // original was 1
MAIN_THREAD_PRIORITY = 3 // original was 3
These lines change the priority assigned to the threads of the fifa.exe process. There are 4 levels available: 0 is the highest priority, 3 is the lowest.
My choice is different from the original and, in my opinion, generates a more smooth gameplay with the side-effect of some audio imperfections and a slower response of the menu (but both the effects are almost not perceivable at all)
Method 2: ( by Mido736 )
1) Go to : My Document\Fifa 12\instance0\
You should find a file called replay0.bin if u don't run the game once and it will be created
2) Delete the file but make sure that the game isn't running
3) Open notepad and click save as .... choose all files from the list and save the file as replay0.bin and close notepad
4) right click on the new replay0.bin and click properties then make it read only file and click ok
You r done when you launch fifa 12 next time it won't create that 800 Mb file.
I have tried both methods with good results...the best way according to me is to do both so that you get maximum performance. I hope this was useful.
Please post your results here.
Feel free to post your questions about any of the methods
