How to solved problem with map filtering?

[Pavel Ushakov]

High resolution (4000x2250) or when camera near glass object - patterned glass looks good for me

Standard resolution (1920x1080) - patterned glass look blurry or not visible - in some parts looks like a simple glass

If i turn off filtering at textures glass looks better but not good enough
Who knows other ways to solve this problem for low resolution renders?

Have you tried using VrayHDRI instead of regular bitmap with the filter set to elliptical?

I cant use VrayHDRI... because i use procedural maps like a gradient ramp, noise and etc
