So I was messing around with DiRT Rally today and I noticed that there is an option called Advanced Blending. This option kills my R9 290! Well it takes my FPS from almost 60 avg to a 30 avg. I Googled a bit for "DiRT Rally Advanced Blending" and I notice that it is supposed to make the trees and grass in the game look much better which I have to agree with. You can certainly tell when it is off.

If anyone else is familiar with this title, what is your video card and performance with this option enabled? It looks too good to leave off, but makes me cry to enable it. If you don't have DiRT Rally it is a phenomenal rally racing title. Gives me the same rush when I used to destroy my grandfather's dirt path and fields in my old Subaru that was stolen.

If it matters I have everything on the highest level including the AA is set to 8f16xEQAA and 1080p of course.
 
I have not played this title yet, I am still playing dirt3. AMD will fix the issue if enough people ask them about it. Have you tried contacting them?
 
No it seems that it is a video card killer for both Nvidia and AMD. It just looks so much better with it on that I was wondering if something like a 680ti or Fury X can handle the setting or maybe even SLi / CrossfireX.
 
I just bought it and installing it now. Gonna test it out in a bit.
Good thing I came across your thread because wanted to get it during steam summer sale but totally forgot about it.
 
Ran the benchmark. 2560x1440 resolution with everything on max including that advanced blending. Used 2x MSAA.

Average fps: 42
Max fps: 75
Min fps: 30

I could see it drop back down to 37 when driving through the forest and going back up when going through landscapes without trees.

Without Advanced Blending I get:

Average fps: 117
Max fps: 143 ( I have it locked to that in Afterburner to stay within VRR, I have a gsync monitor)
Min fps: 100

Yea this option still needs to get optimized so it seems. Early access...

it brings my system to its knees. like 12 fps knees. (5960x, titan x sli @ 1600p).
 
From what little I've read it seems like it's similar to AtoC? It's used in Farcry 3 and 4 and Arma 2 and 3, but the only game from those four that showed any difference with it was Arma 2, but it was a huge difference. It didn't have that kind of performance penalty, nowhere near it.
 
You may have mentioned this part in the Dirt Rally thread, but what happens if you back off the AA settings in favor of the blending? I personally take more of that kind of eye candy over smooth edges any day, but I know I'm in the minority there. I'm just curious what happens if you ditch some of the most computationally intense things (AA/AO/etc.) if you can get all of your frames back with blending on.
