@pilAUTO rain and darkness/long shadows will always be more taxing than nice daylight. The only way to equalize their performance would be to de-optimize the daytime graphics.
Let's say there are probably some optimizations possible (be it some change in approach that doesn't completely change the format of content and render all the current stuff useless, or better options to selectively turn stuff of or make it look not so nice to get better performance (without gaining unfair advantage, like not having raindrops to obscure your vision)), but you'll never get consistent performance across all conditions. Unless you'd prefer it to always run at its worst.
Thank you for your answer Lazza.
However, I agree with you, I'm not looking for night/sunset and rain performance to be similar to a day without rain.
I totally agree with what you say.
I may have expressed myself badly because English is not my native language.
I tell you in a brief way how I adjust my graphics because I find that it is the most profitable visually and that the image is magnificent as well : High-performance VR headset (G2), extremely high supersampling for very high sharpness associated with technology CAS for increased sharpness, X8 game AA, visible AI 6 (good enough for me), rearview cull + particles off + clip 50m, circuit detail ultra, cockpit ultra, texture ultra, PP low,
ALL OTHER GRAPHICS SETTINGS OFF INCLUDING SHADOWS...... some optimizations in the json (max headlight 0, garage detail 0.01, load cockpit opponent off), Nvidia control panel Max quality (LOD bias clamp, texture max quality without optimizations)
and the concession that makes it work : I use the FFR feature which allows me to change the shape of the FOV by increasing the proportions of the horizontal FOV without changing the vertical (oval FOV) and I reduce the size of the FOV by "hiding" the non-essential pixels (compromise) which allows an extremely significant gain in performance.
Also key point, I don't use rain, wet road, sunset/night and I only drive at 01:30 PM.
This set of settings allows for truly exceptional image quality (equivalent to 21.36 Mp before cropping the FOV) :
Ultra sharp, ultra detailed, not aliased, very good performance except in rare cases.
All this to say that I don't expect the rain, wet road, sunset/night to be optimized to the point that there is little difference with the day.
I'm sure you've found that the difference between the two in terms of performance is huge, to me "huge" means excessive.
I just think that a graphics engine optimization effort on these SPECIFIC aspects is necessary and desirable, and
in no case do I expect miracles.
To reduce the gap a little would be really good and frankly necessary.
For my part, if they did, I would agree to reduce my image quality a little to integrate these racing conditions.
But currently, it would be necessary
without any exaggeration to go from the current image quality which is excellent to a really very mediocre quality to hope to integrate the rain or the sunset/rain in my gaming experience, and not both at the same time.
Honestly, that's overkill.
It's really about IMAGER going from a PS5 to a PS3, and again.
