Crysis 2 Demo FOV and AA analysis

#1 Posted by Geno (6477 posts) -

With the availability of certain launch commands, both the FOV, AA and other effects can be adjusted, even though the in-game options menus are extremely restricted. This will be to compare what is available, and what the ideal setup may be.  
 

Field of View 

 
 The game defaults at 55 FOV, but it can be adjusted to numbers such as 90 or 100. You still move at the same speed, but the effect produced makes it seem as if you run faster, which is more in line with the speed of Crysis 1. Additionally, you get a little bit extra viewing area.  
 
55 on top, 90 on bottom: 
 

  
 

  
 

It feels like you're going faster at higher FOV: 
       
Play the above videos side by side, or visit here.  
 
From my testing so far, I would recommend an FOV of 90-100 for widescreen monitors. 
  

Glow 

 
r_glow controls the HDR, skylight and light bloom intensity. Turning it off to 0 reduces the effects. This may be beneficial to people who don't like excessive lighting effects
 
Glow on top, no glow on bottom: 
 
   
 
   
 Personally I prefer no glow, since it leaves the colors intact.  
  

Antialiasing 

 
Using r_postmsaa=0, it is possible to test different AA configurations. The game uses Temporal AA by default, which does a good job on edges but unfortunately blurs the entire image. This part is to compare it with conventional AA, and no AA.  
 
2x2 SSAA on top, default in the middle, no AA on the bottom. If you can, I would recommend downloading the full size images and comparing those.  
 
   
 

     
  
Surprisingly, TAA was able to go head to head with SSAA at less than half the performance cost. It probably has something to do with optimization, since theoretically supersampling should beat out TAA. SSAA affects games differently; sometimes it eliminates jaggies without harming image quality at all (most UE3 games), other times it softens the image in order to do so. Unfortunately with C2, it seems to be the latter. The antialiasing and color fidelity benefits of SSAA are lost from the added blurriness in this case, making it not worthwhile.  
 
No AA is distinctly sharper than the default TAA, but jagged edges are also much more apparent. This is a decent tradeoff however, since you're not likely going to notice those edges while gaming, but an increase in image fidelity will be noticeable (almost like a resolution bump).  
 
I tested with 4xMSAA as well, but it looked worse than the 2x2 SSAA, so it's not really worth mentioning. 
  

From the above, I would personally recommend 90-100 FOV, no glow, and no AA for the current demo and possibly the full game. Of course, my main goal was simply to present the information, so the choice is yours.

bleh...launch commands... 
 
why cant crytek just let us edit it in game!  so ridiculous.

I'm really glad you can bump up the FoV, I often feel disoriented when it's as tight as Crysis 2 has set to default.

As I said before, removing all that bloom vomit makes the game look soo much better.Nice work.

Okay, now I really suspect the FoV number refers to the vertical FoV.  That doesn't look like 90 horizontal FoV to me at all; I'm seeing apparent beginnings of fisheye vision.  Any time you can actually watch something get larger when it goes from the center of the screen to the edges (which I can clearly see in the video), you have the FoV too high, IMO. 
 
I'm going to ask around and see if I can find out definitively whether Crysis 2 goes by vertical or horizontal FoV, but I'm nearly certain after seeing this that it's vertical. 
 
EDIT - Did some googling around.  It's sounding like Crysis 1 goes by vertical FoV, as well.  Apparently its default value is 60, which would translate to precisely 90 horizontal FoV on 16:9.

Yuck, you turned it into a fisheyed piece of shit.

It's not Crysis any more.

@Geno:
 Dont understand the AA thing.
Does "r_postmsaa=0" mean no AA and then  "r_postmsaa=4" means 4xMSAA or  "r_postmsaa=8"  8xMSAA up to 32?
And having nothing in config about AA means 2x2 SSAA.
 
Also FOV 90 gives indeed crazy tunnel/fisheye vision and that the reason it looks faster.
Think the fact that Crysis 1 looked faster is because it was alot faster and im glad that Crytek turned it down.
It made the game alot less like Crysis 1, but better imho if you look at the balance of all the diff modes and just energy management in general.

i dont really see any difference between the different AA pictures ..

Uhh, I think people might be confused about hte FOV in this game.  Bumping it up to 90 would work if it were HOR+ but there has been no confirmation of this and IMO it looks like VERT- so the FOV would be like Bad Company 2.  With 59 being correct for 1920x1080.    http://rjdown.co.uk/projects/bfbc2/fovcalculator.php

r_postmsaa only has two settings I think, 0 and 1 for off and on. After turning it off, you can force MSAA or SSAA through drivers, at least on Nvidia cards. 
 
You and all of the above people mentioning fisheye are correct - it is slightly warped. However, running feels so much better (it feels like you're just running at normal human speed with the default FOV). I tested it out with Crysis 1 earlier today and you do indeed run faster in Crysis 1, but your energy runs out faster too. I think they balanced it now such that you run slower, but can run for longer. I still prefer Crysis 1 for the sheer speed aspect, but I can acknowledge why they changed it in C2, at least for multiplayer. Regardless, I think I'll keep the high FOV as it just makes the game more exciting for me, and I still manage 2:1 to 3:1 on average so it doesn't seem to be affecting gameplay.

So, to be clear, Crysis 2's default horizontal FoV is 85 / 79 / 69 (16:9 / 16:10 / 4:3) - same as Bad Company 2 - which is just a tad low and a bit narrow.  90 / 85 / 75 is generally considered the most balanced and desirable, all three of which translate to a vertical field of view of about 60.
