My MT5 won't disable cores when running a back test, it shows gray and disabled in backtest agent but Task Manager still shows CPU is on 100% all cores
Here is what happened:
I usually run backtest 24 hrs and in the day time I will also use the computer for surfing ,gaming etc.
Week before, I'm running backtest on an Intel CPU 7700K
I can simply turn off 3 cores out of 8 to have a not bad experience of gaming.
Days before I just upgrade my computer to an AMD CPU 3950X
I'm running the same system,same EA on backtest.
Yes it it faster,
I turn on all 32 logic cores in MT5, CPU will run 100% on all cores.
I disable 3 cores in MT5, it shows disabled in MT5,but CPU still running on 100% all cores (except one or two cores will have a zigzag on the 100% line,see attached file)
I'm expecting 3 core complete free for other applications,like it used to be.
There is no other application running at the same time
What I tried
I tried turn off cores usage of backtest agent in Task Manager, it doesn't work
I tried turn priority down of backtest agent in Task Manager, it doesn't work
I assume MT5 doesn't fit AMD cpu very well,or is there any settings need to be set in mt5 or windows?
Does any one have the same issue?
