요새 렉때문에 mm하기 힘드시죠? 제 친구가 레딧 링크 보내주면서 이렇게 하니 렉 없다고 보내줬어요 하기전에 읽어 보니까 사운드 카드 드라이버 업데이트 더군요 그래서 업뎃전에 제가 실험을 했어요 아직도 렉이 좀 있더군요 그리고 나서 업뎃을 했더니..................... 깔끔함! 렉 다 없어짐. 다만 사운드 드라이버를 "리얼텍" 쓰시는 분만 됩니다

How to check if your RealTek Drivers need updating (Note: I'm writing this from a Windows 8 perspective)
Right click on the sound icon on the bottom right-hand toolbar on your screen. Should be right next to the time, and some other random icons
Click playback devices
Locate 'speakers' and double click it
First, ensure that when the ensuing dialogue box opens, that your speakers are being managed by RealTek (it'll say so near the top of the box under 'controller information'
Click properties, then driver. If your drivers aren't from May 15, 2014, running version 6.0.1.7246 then your drivers are out of date
How to update your drivers
go to http://www.realtek.com.tw/downloads/
Click "High Definition Audio Codecs (Software)"
Locate the corresponding driver for your operating system and its bit integer (ie you need to know if your OS is running on 32-bit or 64-bit, or else the driver won't work as intended). Once downloaded, it will restart your computer, then install upon the reboot, and restart your computer for a final time.
Quick note: When this is finished, again right click the sound icon, click playback devices and double click speakers
Click the 'enhancements' tab, then check the 'disable all enhancements' feature. You're not missing out on anything. If you really think you are, then just disable it before you boot CS
LAST STEP: click the 'advanced' tab, and reduce your audio quality to 16 bit 48000Hz (DVD Quality). Again, you won't notice an difference in your ability to track noise in-game, but it will significantly reduce the CPU demands on your computer.
