Yeah, but I did it on fresh install (didn't change anything except ssh, root password and wifi to download q3 port). Today I'll get another keyboard and mouse (however mouse working ok when I connect it to pc). I have few more ideas what may cause that lag, but I'm a little bit bored of changing set...

As stated a number of times above, the Pi 3B+ WILL go to 1400 when loaded (1200 for the 3B), so changing the clock speed won't affect whatever is causing the mouse lag. It's not a CPU speed problem. If its not the mouse poll setting, then no idea what this could be. So I don't know why it's keeps f...

Yes, it does not help me. Ok, another fresh install, and I've downloaded q3. Lag. I setup wifi and root password, and still have lag. Check out again after setup screen resolution (trying 480p, 720p, and 1080p, none of them affect lag) and sound. When I type lscpu in putty I get CPU max MHz 1200 CPU...

Ok, so I added force_turbo line in config.txt, and reboot (all via ssh) and now I get:

blablabla
end kernel panic: not syncing: fatal exception in interrupt

So I think it's time to format sd card and install retropie. Again.

Is it possible to run SiN or Heretic 2? They are using the same id2 engine.

Thanks for answer, this is acually first post that help (helped?) me. I'll check it out and edit this post as my progress will go (or not), About mouse/keyboard lag: In Kodi everything works just fine. I think Dosbox (that SDL or something version) is okay too (I switch from Recalbox to RetroPie cou...

In Recalbox you can change cpu frequency via menu, but it doesn't matter. I check again while playing q3 - when in upper corner shows the temperature warning I have ~850MHz. Still have mouse lag. I added that line about sound, but this doesn't help. https://www.raspberrypi.org/forums/viewtopic.php?t...

Yeah, but I have mouse lag in q1, q2, gemrb etc. I found solution on this forum, but in my case I can't change from 600Mhz to 1400Mhz. Right now I'm watching movie via kodi, ant it still shows 600Mhz via ssh putty. Ok, now I see it - the title should be "I cant set the right cpu frequiency" or somet...

Hello, it's my first post so hi everybody. Let's rock. I cannot overclock my pi 3b+. I'm using retropie (last two months I was using recalbox). When I type vcgenmd measure_clock arm I get 6000000 (600Mhz) The option in raspi-config is disabled (I get "This pi cannot be overclocked" error). I try to ...
