My specs are Acer laptop, v3-571G Windows 7 Home Intel i5-2450M 2.5GHz Intel HD graphics 3000 driver 8.15.10.2669 4 GB RAM With a 2GB NVIDIA GeForce GT 630M driver 8.17.12.9555 I get good fps a lot of the time but near buildings I seem to slow down really badly. I've been through all these sites more than once and tried all their suggestions. http://community.bistudio.com/wiki/Arma2:_Startup_Parameters http://forums.bistudio.com/showthread.php?101124-Operation-Arrowhead-performance-optimizations-comparisons http://www.rockpapershotgun.com/forums/showthread.php?2565-A-few-simple-notes-on-performance&p=76042&viewfull=1#post76042 http://pastebin.com/F7Q8Ne2i Even though some of them suggest opposite ideas. I cant seem to get rid of a huge fps drop every so often and I cant seem to pin down what causes it. I've tried almost every combination of settings with the in game video options, everything on low, everything on high, everything inbetween, and I've added startup parameters and adjusted my cfg and profile, I still cant get the game as smooth as a friend of mine running on a laptop with no GPU at all and just an i7/2gb more ram than me and much higher settings. I dont understand so I came here for help now that I've tried everything I could find in hopes that someone here is using or has used similar gear or has some suggestions anyway. I know I said I tried a lot but please PLEASE any and all suggestions are welcome, I'll try anything and everything and I really want to thank in advance anyone who takes the time to read this and respond. I'll appreciate it a lot.
