Improve FPS | Change FPS Cap
For those of you having a bad perfomance.
Turning of Ambiant Oclusion will boost the performace of Dream. This will be added to the Options Menu soon.
  • Navigate to \Steamapps\Common\Dream\UDKGame\Config
  • Open UDKSystemSettings.ini with notepad.
  • 16 lines down set AmbientOcclusion=True to AmbientOcclusion=False
  • Save and go :)

TO CHANGE OR REMOVE THE FPS CAP
Open "BaseEngine.ini". (SteamApps\common\Dream\Engine\Config)
Find "bSmoothFrameRate=TRUE", "MinSmoothedFrameRate=22" and "MaxSmoothedFrameRate=62".


Here, you can change the "MinSmoothedFrameRate" and "MaxSmoothedFrameRate" values as desired. If you are having issues playign the desert, try cappign the FPS as 24 or 30.

To remove the FPS cap all-together, change "bSmoothFrameRate=TRUE" to "bSmoothFrameRate=FALSE".

I'm not quite sure what this will do, Is this for getting the game to run more smoothly? I always thought it was just slow because it had fancy graphics and was an alpha. I just want to confirm that this is what i think it will do

Generally people with 60hz monitors don't need to worry about doing this as it is already optimized for them, but If they don't have a powerful PC they can try the 24 or 30fps cap to get a steady framerate.

The "bSmoothFrameRate=FALSE" helps people who have a 120hz or 144hz monitors and need to run the game with a much higher frame rate than the default 60fps cap.

sweet, i'll give this a go
Update: this method hasn't made my framrate perfect, but it's soooo much smoother now! Many thanks!

Little bit of a longer post, sorry. It's used to add realism. It's a method to approximate how bright (ambient) light should be shining on any specific part of a surface. It'll make lighting (and shadows/shading, I guess) better. It's kind of hard to explain it and give an example over a Steam reply. It would make places darker (or shadows) and lighter areas in relation to the light source, when it's on. Imagine that, instead of 1 shade of shadow (which sounds wrong), there would be many depending on where the sun (light source) is- like real life.

I found this small example (link), and if you look closely (well, not really that closely...) at this guys cheeks, you can see the difference. This should answer your question. http://international.download.nvidia.com/webassets/en_US/shared/images/guides/sc2-ao/sc2-ao-tychus.png
You can see that with ambient occlusion on is really having an impact on the way the light source works. You can see the difference between the cheek and the forehead on the 2nd half of the photo, as opposed to the faint difference on the first half. I hope I answered your question.

There's a program called Maya which actually renders ambient occlusion in an engine type program in black & white so that no color distracts you. But, I'm sure you know what I mean.
Here's a photo. http://prntscr.com/2s9lk4 The sun is directly above the sphere, but lets say it's far away. The bottom part of the sphere has less exposure to the light source, so it's darker. Now just put that into an entire videogame (or a rendered part of an open world) doing that, and voilà, frame drops.

And, I think I recall Dream having motion blur, would there be any way to disable that? Open to the developers or anyone really.

I might have to try turning Ambient Occlusion off. It looks really nice, but my video card is not good at it, it would seem.
floobadoo99 Feb 19 @ 4:22pm 
I couldn't really tell the differene when it was off, and my video card is pretty powerful so i don't know why i had to turn it off, but it dosn't matter that much

Don't forget to save your changes and make the file read only when you are done editing it!

What about depth of field?
Psychotronix Mar 9 @ 1:47pm 
The depth of field is the distance between the nearest and the furthest objects that give an image judged to be in focus in a camera. When you focus on something, everything around it may become a blur. Here are a few photos for example.

Lets say that the camera is focusing on the character standing with his hand raise. The blur on everything else would be the depth of field... turned on.
Psychotronix Mar 9 @ 1:48pm 
Depth of field happens in a lot of fps games that involve scopes and sights on guns... such as when you scope (usually RMB), most of what is around the scope gets blurry (or at least blurrier than what is inside of the scope).

Thank you Hitman for that explanation, but I knew what DoF is :P. I think DoF in Dream is bad configurated. For me it's annoying to see just 10-15 meters, and everything above is blurry.

Oh, well, then I'm sure it'll answer someone elses question if it ever pops up. And I agree, I'm not a fan of depth of field myself. It can sometimes be cool in games where sniping is present. But, it gets pretty annoying.
