Turning off HDR/PP

[Jambo107]

Though I love HDR/PP its a massive strain on my otherwise decent 7600GT. What I wanted todo is turn if off completely since im running a wide res (1440x900) turning to low only partially turned it off, making using ironsights difficult (20% drop in performance)

So this is what I did to turn off HDR completely, whever or not it disables all features I couldn't tell you, but this did increase my performance noticably, 10-20fps gain in places;

I went to My Doc's/ARMA - Inside theres various files, two where looking for is the name of the profile (Jambo in this case) and ARMA Config file.

First open your profile in notepad, cycle down to PostFX and make sure its set to the following - postFX=0; Save & Close.

Next open the ARMA config file again in notepad and make sure HDR is set to; HDRPrecision=0; Save & Close.

Should now have now no PP/HDR. Hope that helps

Thank you for posting this, HDR is one of the thing that definately is detracting from gameplay especially with the way that BIS has implemented it, where if you look at the sky for like two seconds you for some reason are temporarily blinded barely able to make out things 2 feet in front of you...

Thanks for the tip.

I just tested this out and im sad to say that it didn't really improve my fps at all. Well I take that back it did boost it by 10 but frames still drop to 20 for a few seconds while zooming in, or spinning the view around. Im pretty sure this is a problem with the game constantly loading LOD models and textures (its not optimized very well). Also I wanna point out that HDRI is not entirely disabled, it still changes the brightness of the scene, though not as much as before but its still on.

I still see spots when I close my eyes, I swear you blinded me with those flares last night. When I edit the PostFX setting it only works for 1 game session. After I close ArmA the game resets postFX to 8. What I would really like to see is a preferences launcher like in OFP. Its alot easier to use slider bars and drop down boxes for someone thats not that familiar with OFP/ArmA config settings. Some of the default config values are a bit high. After editing some things like 3d performance and scene complexity I effectivly doubled my frame rate. And yes, we need a way to turn the HDR lighting effects off.

Could you tell me the basics of "3d performance and scene complexity" in the arma config file? I have messed around with them a little but have no idea what they really do. Thanks.

Hahahaha, sorry

I looked in my config files and it doesn't look like these variables changed after launching, I'll try firing up ArmA again to see if I can reproduce this.

Kegetys has already released an ArmA launcher, perhaps he should be contacted about implementing these kind of things as preferences?

This brings up another "WTF?" for BIS: what the hell happened to the external "preferences" program?

You know, you can always set the preference file to "Read Only" after you've set the HDR and PP values. That'll stop ArmA re-setting them to default after closedown

Note: This could be seen as cheating online, so be careful...

Ok lol it doesn't have to be blackdog, please anyone tell me the basics of configuring "3d performance and scene complexity" in the arma cfg. I'm in a tweaking mood.

[Hudson]

I cut my scene complexity and 3d performance settings in half, almost doubled my frame rate but I was having bad crashes in multiplayer tonight when around buildings. Dont know if it has to do with the config edit but I put the default values back in.

[JackHorner]

Never mind I figured it out and doubled my fps
