I have been reading in some of the forums around, and i noticed there's a lot of discussion about proccesor occupancy and framerates.I've been running some different settings and i've noticed some of the options do not seem to effect the framerate or PO at all.
These are my system specs:
These are close to the minimum specs. My idea was, that if there are things in the game that will affect the Proccesor, I would clearly notice that because of my low proccesor speed. After some configuring i manage to get a driveable FPS of 12 on a full grid with some of the most incredible graphics i've seen in a racegame.
Look at Grid_Cockpit picture. The PO will stay around 120 in heavy traffic, but when there's less traffic, the PO will drop down to 80-100. I've made the Grid_T-cam picture at the same session, after i made the Grid_Cockpit picture. I wanted to show you that there's hardly any increase of PO, when you have the arcade and TV-overlay on. I also noticed there wasn't hardly any difference in screen resolution. I've tried it in 800x600, 1024x768 and 1280x1024, with no significant increase in PO. The screenshots are taken in 1024x768.
So, here's my procedure to figure out the maximum framerate.
Delete files f1graphics.cfg and f1graphics.BAK.
Make a backup if you altered f1graphics.cfg and don't want to lose these settings
Start Grand Prix 4 and check if your soundcard is correctly configured. If you are not sure, recalibrate it. Make sure the 2d acceleration is always turned on.
Go to the graphics menu. Make sure cockpit visor, video walls and heat haze has been turned off. Choose the resolution you want to play in.
Select the advanced graphic menu, now let's change the settings:
Click on TEST. Run the test TWICE, because it sometimes gives a lower framerate the first time. (I've noticed that WinXP has an unstable PO, which will lead to a lower FPS when you run the TEST. But it doesn't affect the performance in comparison with Win98/ME, there will only be more peaks. so if you're done configuring, then you can set your FPS a little higher then the TEST result gives you.)
Now you have your maximum framerate with around 100% PO. From here on you can alter the settings to your liking. When you change you're settings, run TEST again to keep the optimum framerate. If you're running an unlimited free practise session, you can set your FPS higher, because the Proccesor only has to calculate 1 car.
I think the maximum framerate could be higher if you fine-tune the f1graphics.cfg file. I'm gonna work on that one, but it will take more time to understand everything about that file. I will let you know, when i figured it out.
