Project Car - Jaggies (AA)

thepharcyde · 11 May 2015 at 09:35

I have a pretty low end laptop these days 650m SLI overclocked to 1150mhz respectively and a i7 3230 @3.2ghz.

Until now I've been playing Assetto Corsa with respectable performance capped at 75fps to mate the screen refresh (overclocked too from 60hz)

However Project cars mostly low/medium settings @1080p

FXAA - does not seem to do anyting apart from hit FPS
SMAA - as above

Both FXAA and SMAA also do not remove the jaggies (pixelated edges) on the white lines on the outside of tracks.

If I turn the above to off and turn on MSAA the jaggies disappear albeit my FPS cannot keep a constant 60fps mostly the start of a race, so first corner normally equals a lot of slow down and certain parts of tracks e.g. start finish grandstands.

In RF2 you could clamp negative LOD that would remove jaggies with zero performance hit.

Is there anything I can do/tweak here or am I simply limited by my aging laptop and it's time a for an upgrade?

Have you tried forcing any settings using Nvidia Inspector? There is an option for FXAA and other forms of AA. The game runs on the Madness engine which was used in the Shift series, those games accepted changes from Nv Insp.

hmm I tried forcing AA from inspector. but it does not seem to have any impact.

e.g. even if I select override any application setting and select 32xS to see if it was working (most performance hit) fps remained unchanged and still same jaggies as before.

Nvidia Predefined FXAA was already on 'Allowed'

I've seen a lot of people use Down Sampling as a means of 'FREE' Anti-Aliasing, not sure if you could do it on a LapTop though, run the Game at 1080p but have the LapTop screen set to 720p.

Hmmmmm, might not make a difference but have you disabled the ingame AA whilst forcing the Nv Insp changes?

Strange how it's not making any effect at all. Is the Nv Insp target .exe file name correct for PCcars? I think there is two different exes for the game, one has 64 in the name. Make sure both are added to the PCars Nv Insp profile.
