Vulkan graphics significantly underutilising cpu compared to dx11

[bpavlov2001]

Just built a new pc with a Ryzen 5 7600X. When I use vulkan graphics I am stuck at 80-90 fps. In comparison using dx11 I get easily over 200. What is strange is netither my cpu or gpu seem to be being particularly used. I am almost certain this is a cpu issue since I used to have this GPU in a PC with an intel i5-12400 and using vulkan in that build didnt change my fps almost at al (it was around 120-140fps.) I have made sure to update my bios and both cpu and gpu drivers.
PC build:

• cpu: Ryzen 5 7600X
• gpu: AMD rx 6600 xt
• motherboard: ASRock B650I Lightning WiFi
• RAM: Crucial DDR5-5600 48gb

i have the same issue even under linux, dx11 is just better for now which is annoying as i want to use anti-lag 2 but cant under dx11, oh well
