How much resolution effects FPS ?

[user33331]

Hello
How much resolution and screen effects FPS ?
I plugged an older system and a game to a full HD 24" monitor. How much does this degrade the performance compared to original 15" 4:3 LCD resolution screens 1028x768 and 1280x1024 ?

NFS Porsche unleashed ( 2000 )
Highest details
0x AA
16x AF
24" Full HD 1920x1080
-> FPS=around 60+ ( Will I get 120 FPS if changed to 15" 4:3 LCD 1028x768 ? )

CPU: AMD 64 3200+ single core (2005)
GPU: HD3650 AGP (2008)
RAM: 2GB

A lot. You'll probably hit above 100 easily on the 1028x768.

Set 1024:768 in-game with that Full HD monitor connected, and you will know.

Look at any of the GPU reviews here. The evidence and your answers are there. In your particular case, who knows? It's old hardware and software reacts differently. A lower resolution will generally put more load on the CPU. Is a single core AMD 3200+ stronger than an HD3650? It's kinda useless asking us when you have the hardware and can easily test it yourself.

"easily test it yourself."
It is not in everyday use. These old computers are cardboard boxed outside in a barn like atmosphere. It is a real Area 51 of computers . 30 years of PC units, accessories and software boxes (the dust is nasty to breathe). I don't know where the old 14"\15" LCD-screens are I know they are there but it might take a day to open and find it and another day to seal the cardboard box and sort the boxes.

Just asked out of curiosity for fast answers.
How about that screen size (inch") does it matter ? (13",....27" ?)
Any modern reviews and test available on internet ?

Inches are 100% irrelevant.
1280x720 resolution on 50" will be faster than 4k @ 30".

Is 4:3 and widescreen LCD screen irrelevant too ? Does stretched view effect speed ?

Will widescreen slow down old computers ?

Screen size is pretty irrelevant
if you play at 1080 x 768 on a 17" screen it will give you the Same framerate as playing 1080 x 768 on a 24" Screen
Only Difference your see is a bigger Picture/blockier pixels.
Change the Resolution and your then see some difference

Just try it. The only thing that will change your performance in a monitor is the resolution.

at a rough guess times one by the other.. this will give you a rough idea as to how many pixels need to be moved around.. roughly it needs twice the power to move twice as many pixels at a given frame rate.. at a high pixel count low frame rate its gpu power.. at a low pixel count high frame rate its cpu power as well as gpu power..

but the simple answer is "a lot"..

That's what she said
