I HIGHLY AGREE. This game sucks for AMD users. Only getting 20-30% cpu usage even in the most intensive times ex. blowing up shit. I have the fx8350 too.

Yeah it's right, the alpha was very good, it's a very nice work for a alpha, but with my new graphic card, a Sapphire HD 7850 2GB, it's very hard to play without lag. In Arma 2 i can play with very hight settings, in 1920x1080 with 3d resolution at 100%, but in Arma 3 i can play in Standard for do not lag
I think the players who have AMD Hardware, need and want a better optimisation because at this moment it's hard to play

Good luck Bohemia and thanks

I have wanted better AMD optimization since I started playing Arma 2.

I have an AMD Phenom II X6 1050T that's over clocked to 3.8 ghz and a Radeon 6870 and I still get fair amounts of lag even with very moderate graphics settings. The game just simply isn't smooth for me and many others with similar hardware.

I did it myself, though I didn't really monitor or check anything in specific. Just thought it'd be a nice addition, if it works for anyone.

I'm sure optimization will come at a later stage though, considering it is alpha and such.

Sadly, that CPU isn't as good as most people "hype" it to be, and its especially not good in Arma, where it heavily uses 1-4 cores. This is not Arma specific, as it is VERY hard to write a game that uses more than that amount of cores, and very few (if any) of the good game developers have done it yet.

Arma is very CPU intensive, due to the actually intelligent AI and the realism, and when you don't have a good CPU (ie. the FX's perform poorly on CPU-intensive games), it doesn't run very well. I had an FX 8-Core OC to 4.5 GHz, and I barely scraped by on 30 FPS in Arma 2. Now with a much better Intel 3770k (without changing anything else), my frames are 50+, most of the time topping out at 60 (w/vsync)

It's not BI's software that doesn't support your hardware, its that your hardware isn't optimized for cpu-intensive gaming.

An higher-clocked i3 will perform better than any of the AMD processors out there, simply because AMD is more for the # of cores (they're more of a server company), while gaming needs more performance per-core.

It's not about software optimization, its about how AMD designs their processors. Sorry guys.

Sorry that's BS, my gen 1 phenom is still spanking i5's

edit: at 140 Watts it ought to, my bus speed helps too, its all in knowing how to setup a pc, you can't just buy a pile of expensive parts and get awesome performance
