General How to fix "Use proper physically-based sampling" that reduces reflection resolution?

Hi. This issue has been bothering me for months since I discovered it.

My issue is when I use "Use proper physically-based sampling" within ReflectionFX, it reduces my reflection resolution to 512 x 512, even though I have set the resolution to 2048 x 2048.

The picture above is 2048 x 2048 without the setting enabled.

This is 2048 x 2048 resolution with the setting enabled. Notice how it does make my reflection blurry (which I felt makes it better), but at the same time downgrade my resolution for no reason.

Whenever I drive using hood camera, it kind of distracts me because I have turned on most settings at max, yet this is the result I get. Does anybody know how to solve this?

RESOLUTION2=512 ; Main resolution (with physically-based sampling large cubemaps can make things slow and mess up shading); "512×512 (recommended)" is 512, "1024×1024" is 1024, "2048×2048 (not recommended)" is 2048
