Fancy desktop PC but unusable even with simfreq all the way down #381

Open RDDE opened 1 year ago

RDDE commented 1 year ago

I'm running v0.1.11a Water cooled desktop PC, win10 with: i9-7960X 64gb ram RTX 2080Ti Very clean windows install.

Running it from the extracted .zip file by just opening the .exe (I'm a simple user, didn't compile anything myself or something)

When I start the .exe, all needles are bouncing all over the place, untill I drop the frequency <6210 When I start the engine, all goes haywire, I get reverbing echos, glitching noises, clipping etc. Turning the frequency waaay down improves the stability a bit but the echos remain, even after stopping the engine.

I've disabled kaspersky antivir for the software.

It was bad with the standard suby engine, but now that I loaded the M52B28, it's completely unusable.

What else should I check? Or is it because my CPU is a multicore and not that impressive when using just a single core?

very sad!

are you running 32 bits windows? because 32 can only use 4gb of memory wich is not very big.

It's a 64bit install.

how fast is your cpu?

I don't know if is is multithreaded for the simulation, I'm pretty sure it is, but your CPU should be powerful enough, but remember that engine simulator really simulates the engine precisely and that uses up a lot of CPU power. Just turn down the simfreq, I have a quadcore intel on one machine that is 8 years old and it runs fine after adjusting the simfreq.

Make sure that you disable power saving on your PC, on desktops the power profile can sometimes be powersave, make sure it is set to full performance and in the bios, set the turbo boost speed of your CPU cores to maximum, so it boosts properly. So many high performance systems today are crippled by powersaving of the OS or BIOS, which is really the opposite of what you want in a powerful system.
