After 3 weeks of problems i decided to make a thread about this. I bought Nitro+ RX 580 8gb special edition (changed with my old r7 260x) and I just noticed huge stuttering / lagging ; dropping fps in some programs (ex : Youtube, Display Settings (after leaving full-screen, moving the cursor left-right it drops the frames and it starts lagging ; scrolling down have drop fps + stuttering). In games it works perfectly I dont see any stuttering / lagging or dropping fps but on Desktop its garbage. The only game that i've seen some problems is Dota2 other than that nothing. I have also done 3DMark (2 Sky Diver Screen capture - ebd19e6159b839dcb4e139d5a613b944 - Gyazo ; 1 Time Spy https://www.3dmark.com/spy/8398999 ) no problems it looks flawless.
What have I done so far ? :
I have no idea what to do so I came here.
The only things that are changed in Wattman are Power limit to 50% and Zero RPM to off.
EDIT (2019) :
EDIT 2 (2019) :
EDIT 3 (9 March 2020) :
Sorry for my bad english.
Try RX 580 GPU at 72 hertz or 60.
If you are using CRU, return to the default.
Do not use Custom Resolutions feature.
Try this and clean-install a display driver.
Thank you for replay.
I have changed it to 72 and 60 hz, same issue.
Reset cru to default, same issue.
Did a clean install with Cleanup Utility, no changes to settings (wattman or other settings) , same issue.
Changed 72 and 60hz after clean install, same issue.
Enabling/Disabling doesnt make any difference both looks almost the same, having it enabled works better
Downloaded and installed that program, same issue.
Go in the BIOS, and return default. Download Windows 1809, clean-install it. For testing, disable Meltdown and Spectre patches with Inspectre and Windows Defender. For testing, will not install latest driver. Try old one.
Thank you , actually something improved (mouse doesnt lag anymore after leaving fullscreen from youtube) thanks to Inspectre. The problem is Im tired of trying versions of windows, did more than 8 versions (1809 too) with old versions for driver.
Idk if this helps but I noticed that everytime I made a fresh windows everything worked fine for 35-50 minutes after that it reverts to my main problem.
Bios settings are default.
Edit : Forgot to mention that this happens only in fullscreen.
