I got 8 GB, but I’ll be damned if I remember the specs tho. I thought something at work too, is it posible that my RAM is the bottle neck? If both processor and GPU have to wait constantly? I have seen a lot of threads about people complaining that WoW uses a lot of memory. Tried playing Witcher 3 and GPU was at 100% most of the time (no surprise) and CPU cores somewhere between 50 and 80 I think. I briefly tested playing with MSI afterburner’s GPU graph on and it was mostly 0 to 100% sharp spikes in exactly equal time intervals of 1-3 sec most of the time.

My ingame fps was allready capped at 60 Thanks, I shall try those programs as soon as I can and see what they show me. I bought new paste today and reapplied, turned out I forgot the golden rule “less is more” and had used too much of it. Thanks for the answers! I forgot to add all the necessary details as proper customer should! I failed to demand to get to speak with the manager My card has AIO water cooler so the temperature was way too high. I felt the cold grip of death for a moment today. Quarantines don’t really feel all that bad to a gamer, until your system starts acting up. And yeah, checked inside the case, every fan that should is rotating.My question here is, can a poor thermal paste application (or old paste?) explain the weird cpu/gpu usage percentages? I did not check how WoW classic used my CPU/GPU before the problems, so there’s no old data for comparison. I tried deleting addons and interface folder etc, removed and reinstalled drivers, nothing. Now look at all the other similar threads and instead it’s allways “WoW uses 100% cpu and 0 GPU” and in my system GPU is much better than CPU and should be the bottle neck. Then GPU use is somewhere between 0 and 70%. Settings don’t really matter, unless I go way down to “Classic” and turn every special feature off. Now comes the weird part: due to this I started again to monitor CPU and GPU usage and now my CPU is allways below 20% and GPU goes straight to 100%, at times cycling between 0 and 100% every second or two.

Well I did the same treatment for GPU aswell, no help, even reapplied the paste another time. After I was done, GPU fan went ballistic after a while and temperature rose over 90 degrees. Now my system is pretty old and I haven’t touched the CPU since 2014 and decided to reapply thermal paste and clean the heat sink. While leveling, my computer fans started to be louder than usual and indeed both CPU and GPU were at quite high temperature (CPU cores 50+ GPU near 90 degrees). My computer is a bit old now, got i5-4460 with Radeon R9 290. Weird issue appeared with WoW classic during the week end.
