by not using outdated time syncing software? ntpdate was replaced with ntpd.

I want to see some of of that riced desktops in action of what users have here!
Gonna want to do some inspiration for my transition of hobby use to full use.

It already does have a big performance impact, on the order of reducing performance to between 8 and 20% of the original performance. No, not reducing by that much, reducing it *to* that much:

Yes, jitter stacks. What, you thought they'd make up for it by returning to you *earlier* the next switch?

Is all this running on a hard real time os?

5. Use an older top-of-the-line CPU.

I'm still using my i7-4790K, which is €170 ($190) on ebay. It's comparable to a Ryzen 5 3600 in single-thread workloads.

Playstation 3, XBox 360, and Wii are very unrelated to the IBM PC.
And squeezing performance was important to all three(especially the PS3).

Meanwhile, the XBox OG is closely related, but emulation efforts have long been halting steps stymied by lack of documentation of the VDP.

Anyway, more bad news if you liked having a real GPU on your Mac: kiss goodbye your Radeons, as Apple is envisioning an "all-Apple" hardware strategy

Sorry for the double-post, feel free to merge it once someone notices me.

Could you find another script that xibalba e-begged off you all, which IIRC was something that would write concatenated text in a CSV to a file?

I think there were multiple versions posted, for C and Python (not sure which version of Python either). I'll take all of them, if possible.

Thank you once again.

While I appreciate your thoughtfulness and effort, my time is better spent picking up a little Python than beating my testicles with a hammer learning esoteric Windows command line tools.

import csv

with open('file.csv', newline='') as f:
    reader = csv.reader(f)
    data = list(reader)

for line in data:
    output = ""
    for index,field in enumerate(line, start=0):
       output += field
       if index < 2:                  # Keep the first two fields but remove , from the rest
           output += ','

    print(output)
