Memory Usage

[kLange 10]

I was curious if anyone else has noticed a cap on memory usage.

While in game I notice that ArmA's memory usage caps at around 900mb. When I first load it starts lower and then the game gradually increases to that point and just stops no matter what is happening in game.

I've tried tinkering with the vram and localvram settings in the config with no effect, this cap still occurs no matter what the value.

The reason I noticed this was I trying to figure out what was causing the issues I have with intermittent freezing after playing for a few minutes, and the graphical issues of textures being blurred after I turn away from them for a second. I thought perhaps the data for that texture was being paged out and the hanging was the result of the data being retrieved from swap. But it does not appear that this data should be swapped out at all since memory usage is so low. Normally I wouldn't care if an application is using less memory, but I feel like in this case it's not utilizing enough.

Was curious if anyone else had noticed this.

Same here, starts to swap as soon as it hits 1gig.

Try adding -maxmem=2047 to shortcut.

I will see if that works when I get home, thank you.

Doesn't make a difference.

The game seems to have stopped hanging...for the time that I tested it. The working set of memory is still capped at around 900 megs, however memory usage does increase system wide (I noticed the cached memory usage increased).

So it seems to have solved the hanging problem, but objects texture's will still revert to the lower resolution when I turn away. It is especially noticeable in urban areas. This game confuses me technically. At least one problem has been solved though.
