TheLastEmp 295 Posted January 6, 2014 (edited) So, I've been extremely frustrated by my FX-4100 Bulldozer running ARMA 2 and DayZ SA like absolute shit over the past year (GPU usage never went above 70% as a result of cpu bottlenecking), and so when I came across a cheap AMD Athlon X2 3.4Ghz I figured why not throw it in my rig and see what happens... Well... It ran even worse... Which I guess I shouldn't be totally surprised by, it was just the my FX-4100 bulldozer was such shit (13-17 fps in cities) I had to give it a shot... Anyway, I take the Athlon X2 out and put the FX-4100 back in and load up DayZ and voila! I'm suddenly getting 100%+ gpu usage and am bottoming out around 28-30 FPS in cities... I can't even begin to understand how the hell this happened but if anyone can lend any insight I would greatly appreciate it... Playing DayZ now is like playing it for the first time all over again because the cities are actually playable. Just so confused as to how this could've helped... or what was going wrong before I swapped the CPU's Edit: System specsMSI FXA-990gd80 moboFX-4100 bulldozer @ 3.8GhzGTX 660 with PrecisionX K-boost enabled8Gb ram @ 16007200 rpm HDWindows 7 Edited January 6, 2014 by TheLastEmp Share this post Link to post Share on other sites
fluxley 2228 Posted January 6, 2014 I've seen a few reports that the rv engine doesn't quite know what to do with the fx series cpu's due to their newer shared module design, basically your fx-4100 will work better is you run with the startup parameter -cpuCount=2 despite it being a quad core. My guess is that installing the dual core athlon automatically set it to use 2 cores and for whatever reason when you put the quad core fx in it is still set to think there are 2 cores. to test you could try setting to -cpuCount=4 and then -cpuCount=2 comparing the results Share this post Link to post Share on other sites
TheLastEmp 295 Posted January 6, 2014 I tried using the startup parameters prior to cpu swapping with no change whatsoever, even tried parking cores 3&4 on the FX and OC'ing a bit further which did nothing... I'll take a stab at it though for curiosity sake Share this post Link to post Share on other sites
