Shift 2 and MLAA

[East]

First create a profile by using the Preset > Add Preset.... Name it Desktop and make sure that MLAA is not selected. Assign a Hotkey if it's better for you.

Next start the game, disable AA in game then exit. Then go to CCC and select MLAA check box. Makes sure you have "Use Application Settings" checked off and have filter set to Box. Then exit out and start the game. This should provide you with anti-aliasing with minimum impact to frame rates.

Use the created profile to remove the MLAA (as it can effect desktop, web browser, etc).

What cards support MLAA? Doesn't seem to be available on my HD4870.

I think 5 and 6 series only

My apologies I should have mention this in the OP. As SonnyXT mentioned that's for the 5000/6000 series card users.

This seems to work properly,but sadly reduces my FPS by almost 50%

MLAA makes everything look blurry and does reduce performance quite a bit, not as much as other methods of forcing AA but it looks too blurry. Not worth it but thanks for the tip!

[East]

I also want to note that you should OC your GPU (leave the memory at stock) when using MLAA. Use CCC's OverDrive feature and slide the GPU to the right. You can create a profile to use both MLAA and manually increase fan speed while gaming. Some use as much as 50% fan speed for games. But that depends on how well your PC case can muffle the sound and how far you are from it.

Well, obviously overclocking is going to improve performance slightly but it's not the end all solution to using MLAA either...

:thumbup:


for me it only works at fullscreen and sometimes disappears, and cause issues in window mode. plus you need radeonpro to take screenshot with it which again sometimes don't want to work with capturing and showing fps overlay.

as east said works with 5k and 6k cards only, XP driver implementation in kinda new with 13.x so that might explain my issues above.

i wouldn't really say edge smudging is "blurry"

for me at high resolutions shader aa is the best compromise performance-wise

image quality is a different thing, although shader aa can reduce shader aliasing (like specular for example) or foliage while MSAA can't. it would be cool if it only apply to foliage and (semi-)transparent objects but a simple edge detection won't work in that case.

it really should be quick though. it you lock 60 fps you need Shift 2 to render 16ms or faster for each frame. MLAA should only take i don't really know 0.5 - 4 ms depending on resolution and GPU speed of course.

jimenez states his MLAA implementation with 0.44 ms average at 1280x720 resolution on a 9800GTX+.

with my (well okay probably 90% is copypaste) DLAA shader i got from 150-205 (no AA) to 135-200 fps in another application at 1280x1024 but it doesn't look that good imho (blurry :glare: )

[East]

^^Good point. The gist of this thread is really to imply to others that when using MLAA don't use in game AA and CCC's AA. Not only will it decrease frame rates but make the game look completely blurry (do to the use of AA). Also, since MLAA isn't free one should overclock the GPU and increase fan speed as needed.

[BlueBlueBlue]

I play at 1920x1200 so maybe the performance hit is greater from MLAA, but either way, it's still forced AA through the CCC and it doesn't look that great.

I think to begin with, the text resolution is a bit low in Shift 2 because my default text looks slightly blurred, so enabling MLAA only worsens the effect.

[East]

Bumping this so that others can try MLAA :mrgreen:

[Kazumi]

maybe not the best comparison. try to ignore changes in heat haze and cloud cover


no AA

same as ingame AA "high", no MLAA applied for me

MLAA is so awesome :-D

Thanks for the pics. MLAA is not blurring up the game. As a matter of fact it's antialaising those shadows and other objects that in game AA isn't (look to the left).

[MaddmattH]

Would an AMD HD6850 handle this game well with MLAA at maxed settings, in 1080p? If so, maybe I'll buy one.
Can't believe my HD4870 seems dated already...

As stated elsewhere as well, MLAA will significantly reduce FPS on my system.

Running at 1920x1200 and all video settings in the game on high except shadows on medium.

Main menu screen shows ~200 FPS without AA, ~100 FPS with MLAA enabled (Use Application Settings, Box, 2x).
In game, hotlapping on Enna, no AI, daytime, ~75 FPS without AA, ~57 FPS with MLAA.

Just a FYI, you don't need to use in game AA + MLAA. You should disable in game AA and just use MLAA as your AA method. :thumbup:

Yep, AA in-game has been disabled in my game from the start ;)

[East]

Almost forgot, you don't need to enable Catalyst Control Center's (CCC's) AA as well. Leave Smoothvision HD:Anti-Aliasing to "Use application settings". All one needs to do is check the box for "Morphological filtering". That's it. No in game AA, no CCC AA. ;-)

shadows look good but i think the main issue with ingame aa is that the thing in the middle of the screen above the car and some other trackside objects don't get smoothed good. that's where MLAA really looks good.

well, 56 FPS means 17.5 ms, 75 13.3 ms. so (correct me if i'm wrong :huh: ) MLAA takes 4 ms.

Which is what is expected? :?: :mrgreen:

I guess I'll have to wait for Crossfire support... ;)

Just to make sure we are all on the same page about disabling AA in CCC when using MLAA. :thumbup:
Adding additional AA would just add to a performance hit.
