Hi all. Thx a million for all your help. Another evening went with fighting these settings, and it just didn't got any better. juppStein. I tried your suggestion. It was really clear that the maxoutputbuffersize had a sound effect to the game. I started with 1024, and latencybuffer in 1. Game sounded clean, but still a lot of latency. Then I jumped all the way down to 128, now the game started crackling really bad, so I increased the value step by step. When I hit 512 the game sounded clean. From this point, I increased the latencybuffer from 1 to 2. But it didn't made any difference, nor did 3 4 and 5. So it didn't make sense to increase it further. Spacy7. I tried your sittings as well, but no luck. I'v been playing guitar for around 10 years now, so I have several amps. Last test this evening was putting a miniJack in my laptop headphone output, direct in a small amp, but still no good. At this very moment, my only idea is to try install the game on my sons gaming PC. Just to hear the difference. Any other ideas from you guys is much appreciated.
