Tomb Raider Trilogy is like *remastered* Tomb Raider Legend, Anniversary & Underworld. You can clearly see Next Level Generation graphics is more evolved from the one seen on Xbox 360 & PC. Plus there seem to be overall texture improvements, both on Lara and the world. You would play this version as PC port is horrendous but supports 60 FPS. The game is nearly playable aside from an issue:
-Some heavy or light FPS drops.
My PC Specs:
Intel Core i7 4790K @ OC
GTX 1080 G1 Gaming
32GB Corsair Vengeance
