Hmmmmm??! Now I am confused
I adjusted my CPU to run at maximum performance
I checked my Nvidia settings to ensure that it was set to deliver max performance.( I have an Nvidia 1080 Graphics card )
I checked the GEM settings to be sure that "intel speed step" was disabled.
Then, I opened IGOR and joined UKGPL4 for a lap at East London in the 68 cars.
I was the only car on track and I had a frame rate of 30 ( max) dropping as low as 12 in places?? I did several laps and multiple restarts but never exceeded 30fps??
Exit Igor and check that I have the 68 exe file listed in Nvidia programme settings and that GPU is set to max......all OK.
Tried Igor again...still 12-30 FPS?
Quit and fired up GPL off line at East London with 68's and 11 AI cars.....instant 60fps and no dropping off.
Igor again and got the IP address for UKGPL4.
Joined UKGPL4 via IP and instant 60fps??
It would appear that it is the interface through IGOR that is causing the fps drop? But I cannot understand how that could be the case??
