just download attached rar file (gta3_full_effects.rar), and copy extracted file (gta.set) to: /sdcard/Android/data/com.rockstar.gta3/files/GTA3
- backup existing one
Basically it is .set file from Xperia Play
and that's it, now all of the effects are enabled (such as car lights, traffic lights, raindrops and a lot more)
See some screens to see difference, normal on the left and with effects on the right.
Some users experience not smooth run or some bug's. I believe this happens if you use this with Chainfire3D, as comes some misconfiguration i think.
For me gta3 run's great and smooth. But mine gta3 works without chainfire3d or any other external app help.
Added original gta.set to attachment for those who want to rollback
Added .set file for Samsung Galaxy SII, if this your's phone, try this one first
