If the following statement is wrong, someone will correct me, I am sure, and I will edit accordingly so as not to add to the confusion.
Render Scaling allows the user to select either a higher or lower resolution to be rendered by the GPU than the display resolution. Ideally we want to have the display resolution set to the monitor’s native resolution for best results.
I understand why I would want to render at a lower resolution and then display the image at the native resolution. Doing this will reduce the GPU workload and so preserve usable performance with a marginal system.
What I do not understand is why I would want to render the image at a higher resolution than my monitor can display. I have a 2060 super connected to an HD 1920x1080 60hz monitor. At native resolution and render scaling at 100% I get locked 60fps performance with my GPU running at around 80-90% and CPU cruising at 60%. I have most graphics settings on Ultra and LOD at 100 for both terrain and object.
The only drawback I currently deal with is that displayed on a 32" monitor sitting about 36" in front of me, I need to zoom in to be able to read the smaller print on some of the instruments just because of screen resolution. Not a deal breaker. I have tried upping the render scale to try to improve the clarity in the cockpit, even though, to me, this seems completely useless. I do not see ANY difference between rendering at 4k and displaying at 2k. Don’t see how it could. My monitor is still only displaying 2.074 M pixels no matter what resolution the picture is rendered at.
There-in lies my title.
- Why would I use a higher render res than my monitor can display?
- Is there a significant advantage that I am missing?
- Other that workload sent to the GPU, are there any significant disadvantages?
- If you use render scaling other than 100%, why?
Please try to keep this purely educational and let’s try not to attack anyone’s opinion.
(Although, this really isn’t an opinion discussion. I would prefer facts and data to help me and others like me understand this.)
