Reddit user fixes Cyberpunk 2077 steam controller input bug through decompiling

Context: the steam controller has a gyro sensor that many use in first person shooter games in combination with the touch pad to have granular aiming ability. This would be similar to how for example one aims the bow in Breath of the Wild. The touchpad typically inputs as "mouse like joystick," an emulated mouse that outputs like an xinput joystick, while ideally the gyro outputs simply as a mouse. Some games take issue with receiving gamepad and mouse input simultaneously. Cyberpunk was thought to be such a game until reddit user /u/oppai successfully followed hunches through the disassembled / decompiled game code to squash a relatively simple input bug, allowing us to use mouse input from the steam controller gyro. In the linked post, said user describes their thought process, the tools they used, and the functions we're looking at in the hex.

Is there any way to turn off the custom css, my eyes are still in 2020.

  If you have reddit account you can disable it in account settings[1]. Reddit Enhancement Suite[2] has an option to disable per subreddit. New.reddit.com breaks all CSS so that's an option as well, I guess.

  Try replacing 'www' with 'old' in the URL.

Also, another Reddit user found that due to incorrect check, it doesn't use all available cores in AMD CPU. https://www.reddit.com/r/Amd/comments/kbp0np/cyberpunk_2077_seems_to_ignore_smt_and_mostly/gfjf1vo/?utm_source=reddit&utm_medium=web2x&context=3 https://www.reddit.com/r/Amd/comments/kbp0np/cyberpunk_2077_...

  It also seems to require AVX which rules out older CPUs - some people seem to have successfully patched it out with a single byte change.[1] I'd love to know what it's actually doing. (note, the hex string doesn't seem to exist in the latest patch) [1] https://respawnfirst.com/how-to-run-cyberpunk-2077-on-non-avx-cpus-error-code-0xc000001d/ https://respawnfirst.com/how-to-run-cyberpunk-2077-on-non-av...

The “old” Reddit version is slightly easier to read on mobile browser: https://old.reddit.com/r/cyberpunkgame/comments/kb73fr/fix_for_virtual_input_not_working/ https://old.reddit.com/r/cyberpunkgame/comments/kb73fr/fix_f... https://old.reddit.com/r/cyberpunkgame/comments/kb73fr/fix_f https://old.reddit.com/r/cyberpunkgame/comments/kb73fr/fix_f...

This is why I don't game anymore. It used to be you popped in a cd and in 10 ~ 20 minutes tops you were playing a polished game. Those were also $60 but a much better deal. Now you get buggy releases, multi-hour mandatory updates for both the console and game (not an issue only if you're in gigabit internet, but some of us aren't), etc.

  I just don't buy games on release. For singleplayer games there's really no reason to not wait a few months for the major bugs to be fixed, or even a year or two to get all the dlc with the game at a discount. I also stick mostly to indie or AA games which don't have this problem nearly as bad to begin with and have new, interesting ideas and mechanics way more often then triple A games that cost twice as much anyway.
