Sorry for my ignorance but what is the custom shaders patch and should I install it? I have all video settings at max (TI2080) and no FPS problems.
Short answer:
You've seen this new ac stuff with rain and night racing that looks pretty awesome?
That's custom shaders patch (CSP).
The creator of content manager started working on injecting new stuff into AC and it started to grow into a community.
This community now implemented dynamic day and night circles by faking the sun into looking like the moon, flipping the exposure levels. Modders made track lights (also fake but looks pretty nice!), then someone found out how to make headlights really shine and make things brighter and visible.
In the end I don't use any of this but there are 2 things that are really really awesome about this CSP:
- cpu optimizations: they managed to optimize the engine to be more efficient for the cpu
- custom font rendering: for John, using his favorite hud apps made his fps go down from 160 to about 40. With custom font rendering and the new hardware acceleration behind it, his fps only went down to about 130 with all his apps!
- other optimizations like forcing the lowest LOD for the cockpits and driver models of opponents (when did you look into another guy's cockpit while racing? Might look weird in open wheelers though! Didn't test yet.
And then, apart from the cpu optimizations and custom font rendering:
- TAA: this temporal anti aliasing isn't like the ghosting one in ACC. It's a sharp, super smooth anti aliasing.
Before I used 8x msaa and forced 2x sparse grid super sampling via Nvidia inspector on top because the shadows, reflections and some transparent objects had way too much Pixel crawling going on at the edges for me during movement.
I'm very easily bothered by this... Back when I was a child all games had msaa and my dad always forced super sampling on top so I was used to jaggy-free image quality.
Anyway, with taa I use 0x msaa, I just turned it off.
Also taa only uses as much gpu power as 2x msaa did but it works 1000x better! There's not a single shadow flickering anymore
Do you use content manager?
If you want my "drive in the dry and during the day and gain the most fps while getting slightly better image quality", then I'll happily Screenshot all my settings.
This means about 10% more gpu load but if you are cpu limited like my old 2600k is, then you'll gain a lot.
There are some traps.. If you simply activate the part that contains TAA, ambient occlusion will be activated too, which reduced my fps from 100 to about 25
Disabled this right after the first go...
