This is not due to the car's location on the track, all the cars were AI driving together in a multiplayer game anyway. I've done MANY tests, and I am SURE it is not that. In most of my tests, I put the view from cars further back in the line, so it works harder to render more cars up front, to get a worse case scenario.
Windows 10, runs the window with focus faster. I can get them all running unlimited at about 20-30 frames, but if I click on one of the LFS windows, it jumps to 120-200 fps. And the others drop to 15-25 fps.
Right now the only solution is to limit them all to 30FPS, so the one with focus does not take over. I tried 50FPS, which almost works, wish I could set it to 40FPS.
I've no idea how to allocate graphics card resources...
Not available on the stuff I am using.
Fire Pro (which is part of my problem)
I do know that only about 10-20% of the Total CPU is being used.
This whole thing is compounded by another problem I have.
I have 2 graphics cards, each with 6 Mini Display ports, so a total of 12.
In my last test, I had 6 monitors plugged into one card, and a 7th plugged into the other card on its own. The LFS window running on the 7th lone monitor, always ran at a MUCH lower FPS, like 10-25FPS, when the others are running 30-100FPS. Even if I swapped and moved a different LFS window to that monitor.
Any ideas as to why that is?!
They are NOT crossfire linked, because that will disable half of my display ports.
If this keeps up I may need to give up on the single server idea, and go with separate NUC computers. And that will just cause electric power demand issues.
I was just since your first post worried about your centralized way, I somehow don't like these things, where single failure takes down everything.
