FPS Drop performance problem

[zelatur]

Hi. Ive got laptop recently its quite good laptop it can handle games like BF4 even on high settings. I decided to install a project reality and i have some performance issues. FPS can drop even from 90fps to 30fps it depends which direction am i looking at.. Tried to change resolution or turning shadows on low or disabling antialiasign it didnt change anything... I remember i was playing this mod on my older pc with AMD FX6100 + GT240 (512mb) and it was fine. Maybe its just laptop some kind of incompatibility ? Laptop specs are i7 + 980m... Please help?

edit: Win 8.1

turn on compatibility mode (winxp sp3). and do this: prluncher->support->place it there. You can also clear shadow catch: prluncher->support <- somewhere there.
Cheers

Your Laptop is fine, it's the game. The game just uses one core of the CPU. A Celeron with same architecture and higher clock would beat your i7 ...
It's all about single thread performance, I recommend at least 3GHz with iCore.
