[Firestorm - Significant FPS drop in 'Sunset' environment setting?]

Advanced lighting with shadows own take serios CPU power.  When you shift and the shadows cascade, and you are not using a I& or I( with serious single thread speed. , it will dip.  Sunset does cause a heavier load (and some other simular) but the hit should quickly even out. The textures and shadowing may be hindered by the lower GPU, see if you can force  setting in NVidia to utilize the CPU rather than GPU for offsets.

Secondlife is CPU dependent, Not as GPU dependent. You do want at least 8 gig video ram for textures, but having a RTX 3090TI over a RTX 2080 won't offera difference due to the old OPENGL used. 

A good I7 or I9 will make a difference when using advanced lighting to maintain stable frame at good draw distance. Or newer AMD chips. 

stable internet and having a SSD to reload cached images helps as well. 

With a I9 setup I can do 180 fps without advanced lights, 60-90 with it on and base shadows, full with vsnch I hover around 60 but there are drops in areas.

heavy traffic areas is another story as its not just rendering that become the issues. Bottlenecks will happen from all factors. 

All we can hope for is a redone viewer system that actually uses gpus in a real way. 

My CPU def makes the difference.  Gpu not so much. So agree. Newer system will be pretty standard with better CPU's (but people need to pay attention to some as not al AMG are the same and have double threads.).  A budget R5 6 core with 6 threads won't perform like the better 6 core 12 thread versions. Most of the 6 thread versions were weaned out. Not that multiple threads really help to much more with current viewers.
