BF4 how to enforce driver-level Ambient Occlusion?

post #1 of 5
Thread Starter 
Hello everyone,

So I never liked the HBAO implementation Battlefield 3 & 4 has, due to the fact it looks a bit inaccurate and 'lively' than SSAO does.

Inaccuracy example: Moving close to certain objects, more specifically certain walls, will create a shadow around the weapon which moves accordingly along with the weapon and in relation to the wall (moving away will have the same amount of shadowing instead of a different one up to a point). The AO effect also appears as if it has lines of shadow rather being a more composite and complete shadowing effect (as it should be).

Lively AO example: If we say that we have 3 AO liable objects (x,y,z) only the x-AO liable object will flicker when it is either repositioned by the engine or is repositioned (on-screen) due to user movement. However, this is not the case in other games, as I have only noticed this in Battlefield 3 & 4. And although SSAO works as it should and as AO is intended, it is not as rich, hence not as satisfying for me.

My question is: can we enforce HBAO Quality (medium) or HBAO High Quality (high) through the Inspector in some way and see how the driver will handle it, or maybe even enforce HBAO+ if possible?

I bet someone would know what kind of profile changes have to be made in order to achieve this (e.g. determine Frostbite engine flags).

If anyone is interested on discussing this, I would appreciate it.

Thanks!

I don't recall anyone having any success forcing anything in BF3 MP through drivers so I expect the same results here. I'd suggest finding other Frostbite engine games and trying out there AO compatibility bit with BF4 for starters. People usually have to go through a lot of testing to find these bits that work with inspector settings. Up to you if it's worth it or not.

List of games. http://en.wikipedia.org/wiki/Frostbite_(game_engine)

Check the drop down menu at the top of inspector to see whats there.

Did no one do this already? Well, that is peculiar, I was expecting that someone would already know the most compatible and high performing profile by now.

Thanks for your input though, it did not occur to me that a list would be available on Wikipedia, I will test on my own and hope that someone will find the interest to further discuss this in this thread.
