New FEAR SLI Profile

[SH64]

Since the built-in profile was producing some bugs & very poor Softshadows (SS) performance i had sometime messing up with the SLI settings to come up with a better profile than nVIDIA's own SLI profile! yes thats right & i tested it for sometime along with other members (thanks OWA & White|Mute).

the SLI value is : "2400801" (AFR2)

with this value expect :
1) Decent improvement without SS. (i got around 11% increase)
2) Huge improvment in performance with SS enabled (i got about ~150%!)
apperantly SLI didnt work with that built-in profile .. it even ran slower than single GPU.
3) Flickering white line can be seen sometimes in the middle of the screen due to SFR mode. Fixed!
4) I've noticed some slowdowns with intense shooting in slow-mo. Fixed!
(some users might think its usuall .. FYI no its not!! its an SLI bug)
5) Shooting through waters produce a very low framerates . Fixed!
(thats another SLI bug .. for exmaple it dosent happen in single GPU mode)

it worked flawlessly for me except for some jerkiness in the main menu , but thats it. its experimental profile afterall & some people might come up with even a better one
for the time being though i recommend it for every SLI user.

So...sorry, I'm still new to this whole profiles thing...how do I go about setting this up?

Hi thanks for this! Now, how to use the profile? Just update nvapps.xml or do I need to do something else too?

[SH64]

Ok first since FEAR has a built-in profile .. you need to override it by creating a new SLI profile for FEAR in the nvapps.xml located in system32 folder.

you can add new profile there manually or theres a program called "nvao" (or nvSLI optimizer) that creates SLI profiles with no hassle though i cant find a place to download it right now. maybe if someone can help me upload it ? (its ~250kb .zip file) .

after that go in the control panel & apply the profile by selecting it & modifying the options & all that stuff then press the "apply" button.
make sure to enable the GPU balance bar aswell to make sure the profile is running correctly ( you should see a vertical bar which = AFR .. horizontal bar means you're still in SFR & something is wrong .. like profile isnt applied correctly).

Like this?

<PROFILE Label="F.E.A.R.">
     <APPLICATION Label="fear.exe"/>
     <PROPERTY Label="multichip_rendering_mode" Value="2400801" Itemtype="predefined"/>
</PROFILE>

So you have to have 81.87 for this to work, I take it?

it should work with whatever 81+ driver .. i'm using the 81.85 , OWA used 81.87 i believe.

[superklye]

oh, because I've got 81.84 and I see no existing Fear profile in the driver list.

You will not. because FEAR is a wierd case .. it has no standard SLI profile in the list yet.

:-\ Now I'm really confused, because in your first post you said:
