ComangliaJDUnwinDoing a realistic report since I doubt most people close everything to play a game these days.
Intel 4770 i7 3.4ghz
3x 1200p displays
TF2 running in Borderless window 1200p
8x msaa fsaa
Highest quality settings in general with only a few performance tweaks
Open apps, browser, rainmeter with system monitors active, several nero instances, hexchat, downloading through steam, jdownloader, multiple explorer windows, command prompts, steam chat group window, 4 virtual desktops.
Results while multitasking, playing a movie on another screen
I put in bold all the things that I doubt most people actually have open/have/or use while playing a game. Seriously "several nero instances" who burns a DVD / rips images while playing games in 2018? Who uses jdownloader in 2018? 4 virtual desktops... More than 2 displays? Also who watches a movie while gaming? mat_picmip -10 doesn't work -1 is the highest quality option available even with sv_cheats currently picmip can be -1, 0 , 1, or 2. Finally, 8x MSAA and 8x FSAA???????
I mixed terminology by mistake, I understood msaa as a form of fsaa which is wrong.
bd-r backups are still useful for long term backup storage, cost per disc in spindles is rather cheap when on sale now.
Jdownloader is still useful for simply ripping youtube channels and other things, even in 2018, its more convenient than youtube-dl most of the time.
And of course more than two displays, that's what monitor arms are for.
Just doing something different, because most people don't clean boot to run a game these days.
