There is a perceptible lag between moving a control and a response from RC8 which is not present in RC7, I estimate between 1/10th and 1/5th second. That is sufficient to render the simulation unusable for my purpose (F3a practice). All aircraft are affected and the effect is visible in the menu item Controller/ Assign Controls (Advanced). There is no visible lag in RC7 nor in my OS joystick test app. I have tried changing the servo speed setting for one of the aircraft servos in the vain hope that it might have an effect on the delay, but it does not. I am using the same event-based controller in RC7 and RC8. I would be grateful to hear from anyone who has experienced this, especially if they have a fix, or from anyone whose install does not have this flaw so that we can compare setups.
Comments gratefully appreciated.
