We've previously covered some mods for GTA III, but they required you to tinker around and replace files manually. Thankfully, forum member hacksteak25 developed a little application that allows you to easily change some of those settings, for example by making the resolution lower to make the game run smoother, and even automatically backs up the standard settings file so you can recover should GTA fail to start.

Available Settings:

• Shadows: On/Off
• Lighting: On/Off
• Resolution: High/Low
• Rendering Distance: 18 Steps
• Blur: On/Off

Head over into the forum thread to grab the APK.

Thanks to TamCore for the screenshots!
