Issues fixed

Smoothed frame rate

Many Unreal Engine 3 games use a built-in frame rate limiter with a default value of 62. Users with a strong PC may want to change or disable this limiter.

High frame rates may affect in-game logic in certain games, leading to various glitches of varying severity. See each game's individual entry page for details.

Increase the frame rate limit
Open xxxEngine.ini with a text editor Change bSmoothFrameRate=False to bSmoothFrameRate=True Change MaxSmoothedFrameRate=62 to MaxSmoothedFrameRate=XXX (XXX = Your desired frame rate limit)

Disable the frame rate limiter
Open xxxEngine.ini with a text editor Change bSmoothFrameRate=True to bSmoothFrameRate=False

Some games reset values to default after launching the game. In such cases, you can set the file to Read-only.

Some games may crash with their .ini set to Read-only.
