I play an older game which is called Silent Hunter 4. I've been experiencing bad lag in the game since I reinstalled it on my computer awhile back. I honestly don't know if there is a cure, but I thought I'd ask if there might be a solution I might not have thought of. Things I've tried is different drivers (older and newer), going from a third party sound card to onboard sound, have tried both Nvidia and AMD GPUs, and many other things too numerous to mention. I should mention I don't seem to have any problems with the newer games I play. My computer specs are as follows. 850w PSU Intel i7 6770k (no OC) Asrock z170 Gaming 6+ Asus GTX 970 Strix 4 GB G.Skill DDR4 3200 16 GB Samsung SSD Evo 850 250 GB Samsung G29C790 29" The reason I'm asking about this other than the fact the game lag is very annoying is the fact that SH4 is my all time favorite game and it keeps drawing me back to play.
