To further elaborate. To match a 60hz CRT display you would need around 1000hz on a sample and hold display because of how the phosphors on a CRT work. Also you need a high resolution, 4k or above, 8k is the ideal, in order to properly render a simulation of the slot mask and phosphors. Simulating a CRT properly is no easy task and its also GPU intensive.
If you really want to play your games the way they were intended then try and find a CRT, they are pretty cheap if you aren't looking for one of the meme ones that all the redditors are after because of that stupid digital foundry video. The motion clarity on a good CRT is still unrivaled even compared to OLEDs.
