Don't Sleep to Sync in Non-VRR Normal Running State (#16189)

The check for sleeping to sync to a specific speed that is meant for fast forward/vrr could be true for a non-vrr normal core running state causing a possible sleep in a situation it was not intended for, especially at higher hz, and thus interfering with frame pacing.
