Latest 527 patch causes 4K video preview lag and cannot render 4K

I have been using Vegas Video 18 since December on a new PC build (specs below). Even though my graphics card is outdated, I could select Legacy decoding options and my video preview was fine for 4K. For 4K I would have to change my video project settings to 1920x1080 as a workaround).

After the recent 527 update all of a sudden no matter what I do for the video preview settings, the video preview lag for 4K is horrible! Nothing helps: not the 1920x1080 project settings workaround, nor increasing the video preview ram, nor the Legacy decoding options.

I know I need a new GPU but we know what the market is like for GPU's! So that's practically impossible.

Any thoughts? Am I the only one experiencing this issue?

Specs:

Windows 10 Pr 64bit (latest build)

Intel Core i9 9900KF

NVIDIA GeForce GTX 770 (was rendering 4K fine for the past 6 months until now)

32GB RAM

Latest SSD drives
