Now last year i never had this issue or be for season 7.
It seems that the game client is taking more Cpu then it should.
For a AMD Athlon II X2 3.20Ghz there should be no reason way this should take up 80 to 90%of the CPU at the most the game should only take 50% or 60% There has to be a issue some where in here.I have 8Gigs of ram.
I even tried to Adjust the Video settings to pretty much nothing and it still took about 70%.
And when you first go to load the game with the Black splash screen it will spike the cpu at 100% for like 3 mins.Is there a reason way this game is taking up so much CPU power.You would figure that for a game that is taking up 90% of a Dual core it would load a lot faster.
But it seems even though the game is take up to 90% of the Cpu it seems to take a longer time to load a lot of times i do not get it.
And i have a 10mb connection.
AMD Athlon II X2 3.20Ghz
8.00 GB Dual-Channel DDR3 @ 666MHz (9-9-9-24)
1023MB GeForce GTX 550 Ti (EVGA)
With an old Q9550 (quad-core 2.83 GHz @ 64-bit) I go from about ~30% CPU at launcher login to ~100% CPU when it gets to the Chevron image, then about ~20% CPU at character selection. Depending on the map I'm in, CPU tends to go from about 50 - 60 % CPU.
There are a few GPU/CPU options in the advances video options tab ingame (the button to open the advanced settings can be often missed, it is at the very end of the video options page, and you need to click on it to expand the options inside). I suggest you try out the following:
