Hi thanks for getting back to me! Full laptop specs: Processor IntelĀ® Core i7-2630QM CPU @ 2.00GHz, 2001 Mhz, 4 Core(s), 8 Logical Processor(s Physical Memory (RAM) 8.00 GB Total Physical Memory 7.85 GB Available Physical Memory 5.43 GB Available Virtual Memory 7.13 GB NVIDIA GeForce GT 540M Adapter RAM (2,147,483,648) bytes HDD Free Space 646.54 GB (694,216,138,752 bytes) It's no spring chicken but I just reformatted it and was expecting to get better graphics on that than my old Xbox360, not substantially worse with 15-20fps! Laptop was plugged in (never use it unplugged now). That's a good find with the ini file! It's still slowing as "IntelĀ® Graphics 3000" which sounds like the integrated to me. How do I reset/override this? I wouldn't know exactly what to type in there for it to pick up my NVIDIA GPU. I could reinstall completely but I just downloaded and cleaned a load of mods (currently all deactivated whilst I sort the fps issue) which would probably all need redoing!
