After I've had the game open for almost spot on 2 hours the game's CPU usage as reported by task manager increases to at least double what it was moments earlier. It starts frequently dropping out of realtime and the UI becomes laggy. Even just sitting at the main menu without having loaded a track, the usage went from ~5% to more than 50% after the 2 hour mark. Has happened on two PCs: 1. Windows 7 x64 | i5 4690, 3.5GHz | 16GB DDR3 | GTX 1080Ti 2. Windows 7 x64 | i5 4670, 3.4GHz | 8GB DDR3 | no dedicated GPU
Do you have any other information about this, such as maybe a log showing memory usage (system and GPU)?
