Actually Bryce is running at normal priority when it's the front most ( current ) window. You can verify that by launching Bryce, then launch task manager (Ctlr,Alt, Del ) if the base priority isn't displayed in task manager go to View/Select Columns and enable it. Then look at Bryce in the task manager window ( it will say low ) Then click on the Bryce Icon on the task bar, ( Makes it the current program ) and the Base priority will change from low to normal. How to change the priority to high and make it stick I don't have a clue. One suggestion I would make to you, helps over all system performance. With all the name brand computers I've owned, they have many processes launched at start up, many of which are never/seldom used. They are basically just eating system resources. ( I had a HP that was down to 69% free system resources at start up ) You really want to get that number in the high 80 or low 90. If this is a new computer call tech support, and tell them you want to know exactly which programs/processes are absolutely needed to run at start up. And how can you clear the not needed programs/processes out so they don't launch every time you start the computer.
