Thanks.
Nearly everything we do here can be considered niche/bleeding edge/experimental.
I don’t think WindowCast recommends 640 x 680 resolution.
It recommends finding out the native resolution of the content i.e. 1 x resolution scale.
I think it’s best to let your eyes be the judge for what you think is the best resolution to use.
If you try 240p, you’ll probably get the most defined and visible scanlines.
At 640 x 480 the scanlines tend to disappear or almost disappear.
There are pros and cons to either approach. Higher res can lead to less aliasing but scanlines also help reduce the appearance of aliasing as well.
You can get the best of both worlds using the latest Mega Bezel Reflection Shader or CRT-Guest-Advanced shaders which now have support for Hi-Res Scanlines (Hi res graphics + regular lo res scanlines).
Since I have so many different preset offerings, I can’t really give you a one size fits all answer for this question.
You can probably try my latest Sony Megatron Color Video Monitor preset pack using HDR Mode and see if you like it.
Once you have that setup and running correctly, feel free to introduce BFI and see if the cost/benefit is worth it to you.
What I would say though, is that if you’re used to whatever motion clarity you’re experiencing now without the use of BFI. Using it can spoil you, making you more sensitive to motion clarity issues and it could be hard to switch back.
The main downside to this is that you’ll always lose brightness when using BFI and brightness is essential to making most of my presets look good on any display.
So my presets have been tuned for around 600nits, which is the minimum recommended brightness for Sony Megatron Color Video Monitor.
If you use BFI and go below that, you might gain better motion clarity but ruin the visual experience in other ways in the process.
So to enable any type of BFI while preserving the best of both worlds, your display really should have an insane amount of brightness headroom.
Browse this thread especially the first post. Read the readme files of my preset packs and look at the RetroCrisis videos, especially the most recent one to figure out how to set things up correctly.
Since you’re using an 4K LG OLED TV, which is what most of these presets were designed on, you shouldn’t have much setting up to do on the Shader Parameters side but you should still calibrate your Peak and Paper White Luminance to what your TV supports for the best possible experience.
My highest quality presets are my Sony Megatron Color Video Monitor presets and those can run on a cell phone or Raspberry Pi4.
The Mega Bezel stuff can be a little resource intensive if using the higher performance tiers but I run those on a GeForce GTX 1070.
Remember Rome wasn’t built in a day so take your time to learn things one step at a time.
By the way, you can also apply CRT Shader effects via ReShade. CRT-Royale, CRT-Guest-Advanced as well as Sony Megatron Color Video Monitor all have ReShade ports.
