I updated to Blender 2.82 and now eeve render just like a normal renderer and not realtime. Before in Blender 2.81a took me like 10 seconds per frame with a lot of obejcts. Now with just one object and two imported obj files it takes like 2-3 minutes. I reverted back to the 2.81a version and now is behaving the same!
MY PC specs are:
AMD Ryzen 3 2200g with 32Gb ddr4 2666 and two ssd 1Tb disks
My GPUs are Nvidia GTX 1050Ti 4Gb ddr5 and Geforce 1030 with 2gb for the monitor.
I reduced the samples in Eeve to 16/16 and turned on D-Denoise and viewport denoise and still is slow. I could do 900 frame in 10 minutes and now I spent like 6 hours just for the same 900 frames
