TSX instruction for i9 9900kf

Hello guys, I would like to know why I can't find the TSX instructions on my 999kf i9 processor, and in the processor specifications it appears that it has TSX. I need it for an emulator and without these instructions I lose a lot of performance.

I currently use a MOBO Z390 UD with the latest BIOS version available.

Hello, thanks for the feedback.

I had already seen this thread before sending my question, but it did not help me. According to the responses, the problem was with the emulator that was probably out of date, but as you can see in the attachment I sent, the instructions do not appear anywhere, regardless of whether I use the emulator or not. My processor definitely doesn't have the instructions. I already tried a line of code that was supposed to activate the instructions, but it didn't work.
