Building a 3 Screen Setup using Pixel Budgeting

post #1 of 6
Thread Starter 
So the setup I will be building now is:

CPU: Intel i5-3570k
Case: Thermaltake Commander
GPU: EVGA GTX670 4GB
RAM: PNY 1600MHz 2x4 kit
HDD: Seagate 1.5TB Barracuda Green
Mobo: MSI Z77A-G45
ODD: Lite-On Internal 24x Dvd Writer
PSU: Cooler Master Silent Pro M850 (GOT IT)
CPU Heatsink: Cooler Master Hyper 212+ (GOT IT)
Case Fans: SilenX Effizio 120mm Blue LED Fans (x5) (GOT IT)

I will be using 3 dell 1440x900 screens in order to do this setup since 1. I don't have much space to my disposal and 2. I want to be conscious to the electricity bill. There are other reasons, but those are my main ones at the moment.

With that being said, I wanted to post my pixel budgeting theory. I personally have had a 1080p screen side by side with my 1440x900 screen and saw no difference (I blame anti aliasing for that biggrin.gif since anti aliasing is practically false resolution). Not to mention I love my 19" 1440x900 screens, I am always up close and personal to them anyways.

Anyways. Here is my theory using Battlefield 3 as the benchmark:

BF3 with gtx670 is 58.43fps on ultra (using smaa not MSAA or FXAA) at the resolution of 2560x1600. BF3 is 100.77fps on 1920x1080 on ultra (using smaa not msaa or fxaa). Resolution I will be using with my 3 screens is 1440x900 each. 2560x1600=4096000 pixels. 1440x900x3=3888000. I will be running battlefield 3 on ultra settings at 60fps solid. on the resolution I am running at.

BF3 Maxed (SMAA)
1920x1080 = 2073600 pixels. 100.77fps
4320x 900 = 3888000 pixels. 79.6fps (3 screens)
2560x1600 = 4096000 pixels. 58.43fps

My question to you guys is am I doing this right? Will having 3 screens affect the video card rather than having 1 giant 2560x1600 screen? Please discuss. I need as much info as I can before I jump the gun on this idea.

Based on my theory that I will be testing within the next two months:

Crysis 2 Ultra Spec (DX9/DX11)
1920x1080- 88.4 / 64.6
4320 x900- 64.4 / 50.1
2560x1600- 48.4 / 35.6

Dirt 3 Ultra Spec 8xMSAA
1920x1080- 92.85
4320 x900- 76.30
2560x1600- 59.75

Metro 2033 DX11 High AAA
1920x1080- 89.33
4320x 900- 71.17
2560x1600- 53.00

Skyrim Ultra w/ FXAA
1920x1080- 86.28
4320x 900- 72.28
2560x1600- 58.28

World of Warcraft Ultra 8x AA
1920x1080- 117.98
4320x 900- 98.86
2560x1600- 79.79


I am not sure if these measurements are accurate or not. Right now it is just numbers to me that I need to test when I build the rig. I also have to consider the fact that I will need antialiasing for three screens rather than one now so that might decrease the framerates a bit.

The aliens are retaliating from the amount of research I have learned about their settlements and what kind of technology they use. One thing is for sure that they know how to optimize their infrastructures so they recieve more longetivity out of their systems.

I just realised something. No matter how many screens come into play, what matters is how many pixels are being antialiased when using antialiasing.

If I use 2073600 pixels (1920x1080) stretching across 3 screens without changing the amount of pixels being rendered from the graphics card, it will still be 2073600 pixels being antialiased.

So if the amount of aliasing is only relative to actual pixels rather than how many screens, there should not be an issue for antialiasing. Or should there, since there are 3 times as many things showing up on screen. Would that mean that the antialiasing algorhythm need to antialiase 3 times as many models or would it still be the same.

I will more than likely be using SMAA rather than MSAA or FXAA for my games, so I don't get that performance hit anyways.

When I get this rig and build it, I will show my results.

END LOG...

EDIT: I will also add screen shots of MSAA vs FXAA vs SMAA for multiscreen gaming and the performance hits relative to the image quality. Stay tuned biggrin.gif
