So i have a pretty decent rig i would say - nVidia GeForce GTX 750 Ti OC, AMD FX Quad Core 4170 4,2 GHz, 1 TB hard disc, not sure about the mother board and a 4 GB of RAM. Yesterday i downloaded Dying Light. The game works almost perfectly fine when i look in one direction, but as soon as i turn around or start rendering some new stuff i get lag spikes untill everything is rendered. Then it goes smooth again. Please, tell me if the RAM is the problem because i am looking forward to GTA V, i pre-ordered it already and i don't want a bad expirience with it. Thank you!
