Ikaruga 10 Posted July 21, 2010 (edited) Hi all As said in the title, Arma II Vanilla works great on my PC, but I installed (and applied the lastest patch to) OA yesterday and it's absolutely unplayable, even with all the graphic options at the lowest. On the title screen with an empty world (just the sea and nothing else) i get something like 10 FPS at best. My specs: AMD Athlon 3200 + ATI Radeon HD 4850 2 GB RAM Can someone help please ?

Max255 59 Posted July 21, 2010 Jeez, is that 1 core CPU? What frequency? Share this post Link to post Share on other sites
Ikaruga 10 Posted July 21, 2010 No, wait ! Sorry, wrong CPU ! That was my previous one ! I'll post more accurate information when I'm home ! However, whatever my CPU is, Arma2 works fine and OA does not ... Share this post Link to post Share on other sites
seelix 10 Posted July 21, 2010 Even if you have a proper CPU,you definitely need more RAM ! Share this post Link to post Share on other sites
bono_lv 10 Posted July 21, 2010 Yeah, you need more ram and I'd suggest better cpu too. But meanwhile try to add to start up parameters -cpucount=4 (2 if dual-core cpu, ofc if you have multicore cpu...) switch. That fixed all my performance issues with Arma2:OA.

Ikaruga 10 Posted July 22, 2010 Updating my GFX card drivers solved the problem : now ArmA2 OA runs as fine as ArmA II vanilla, maybe even a little better. Thanks to everyone for your help. Share this post Link to post Share on other sites
