Ladies and Gentleman,
especially @
AccAkut and
@Phoenix77.
I have made further troubleshooting as I myself had some sound issues as well. In the beginning, they did not annoy me. But the longer I try to enjoy the track, the more it annoyed me. I also had those spikes every 4 seconds. However, I did not have the issues constantly every spike. When I had issues, they where either clicking noises or sound was gone for 1 up to 4 seconds while the game continued normally and also reacted to input just fine.
While testing I found, that I had the same issues offline as well. I did cross check this with official tracks. What I found is, that the issues are caused by a high load on the main track. On Kunos tracks, those are around 12 to 25 percent (for me that is). Online on LA Canyons Freeroam the load was constantly over 80%. Offline was no different.
I put some thought into it and may have found the issue. How? I use another ingame App which displays the whole map.png file at once so you can locate every player easily. What I noticed is, that the track is almost invisible on this map app as the lines were very thin. What is causing this? Of course, downscaled high resolution images. When I checked the map.png I was quite shocked as it has a resolution of 16382x16382. The horror! Such huge textures are really bad for graphics cards, especially if you do not own the latest model!
I have downscaled it to 8% and what would you think, my Issues were gone offline and online. Offline, the main thread is now down to 20%-30% load. Online on the server it's between 50% to 70%. My frame rate also kind of doubled while I had the chance to increase my gfx settings.
So please everything with some kind of issues on this track, please try the attached map.png file. Replace it in /la_canyons/freeroam. Please tell me if the issues are gone or are appearing less often. If so, Phoenix should include a downscaled version of this png file in the next update.
