Hi,

Thanks very much to those of you that posted your specs and issues with ATI cards in FIFA 11. The below may assist you in resolving the issue. Please note that we do not recommend that you mess with the rna.ini file but this may 'unofficially' help you.

**IMPORTANT** This is only for ATI / AMD users who are already seeing the game at 60fps in game play (with V-sync on) but still see stuttering. This will NOT simply improve your framerate.

Step 1:
Open the rna.ini file. If you do not have this file, you can create it by opening a txt file and renaming it as rna.ini . You will need to place it in the same directory as where the fifa.exe exists.

Step 2:
Add this line:
SCREEN_SLEEP=16

[简单汉化]
对于那些fraps明明显示有60帧却仍然感到顿卡的玩家，这个办法可能有用

步骤1:
在fifa11/game/下新建rna.ini文件

步骤2:
在rna.ini中输入
SCREEN_SLEEP=16

注意
只适用于已经在游戏中达到60fps的玩家，且必须打开垂直同步。这不是显示优化，并不会提高你的fps值。
另外，原帖提到是针对ATI显卡的用户，但我发现了回帖反馈中有N卡用户，具体未经测试。
希望能有网友汇报情况。
