This is just temporarily so they can focus more on the important stuff.
(A developer said that in one of the showcase videos)

(Some options like anisotropic filtering or anti-aliasing can be incompatible with several graphics cards at the current state of Arma 3)

Hmn, those specs should run just fine with Arma 3.

Try to deactivate special effects in the Arma 3 options and put everything at the lowest quality just to check if the problem does still occur.If it's gone then, try to find which option lets the bug appear
and report it.

Also newest graphics driver already installed?If not: http://www.sapphiretech.com/presentation/downloads/download_index.aspx?psn=0006&lid=1

This problem is unknown to me, looks like a hardware - game issue.

System specs?

I guess they are only a kind of placeholder at the moment, I am 99,99% sure they'll improve the explosions during the development.

But for now there are more important things than explosions.

That's pretty weird, my system isn't that good as yours and I can run Arma 3 on high - very high without problems.

Do you have any programs running in the background while playing Arma 3?Like an anti virus or tune up software?
If yes, disable it and check if it increases your fps.

Also, I don't know if it's helpful/working in Arma 3, but try to add "-maxmem=4096" and "-cpuCount=4" as parameter.

Ah, nevermind, I thought he was just advertising for the crack or something.
My bad.

I hope there's also fade protection in Arma 3.
Are 33$ that much for a great game?..

It's not non-usual for Arma.
System specs?

To improve your performance try these parameters (without the "):
"-cpuCount=#Insert the number of cores your Cpu has#"
"-maxmem=#Insert the number of Ram you have#"

For example
1GB = "-maxmem=1024"
2GB = "-maxmem=2048"
3GB = "-maxmem=3072"
4GB = "-maxmem=4096"

Could be, but in the showcase videos Bis presented this as a feature; For stealth missions etc.
Not sure if this is a mission depending feature.

I would really like to see female soldiers in Arma 3, I mean, in real life during a combat you can't just say "Ehh there's an armed female in front of me/us, I don't want to shoot her", because she'd shoot you then by the next best chance.

There are females in combat zones and in the army, maybe not that much as men, but there are females, so should they also be in Arma 3 then.
