My experience, from a short try-out:
1. FPS is definitely improved, and panning around is smoother.
2. Blue triangles are reduced or eliminated
3. Terrain texture blur starts much closer, making it very noticeable compared to the settings I used before
4. I don't know about microstutters, but the megastutters when an RAF formation first wades into a formation of bombers are still there.
I'm currently using a variant with just the extra stuff in the preload.xml file, as I prefer the previous sharper terrain textures.
Thank you for the feedback Lima. I will test the WOTR tuner package with the compositescenerybudgets file available in ver. 1.3 of the tuner package for WOFF - since that one slightly improves distanced textures - and will include it with a new ver. of this tuner package should the improvement be noticeable. If there are no major differences I will leave the tuner package for WOTR as is, and everyone is welcome to tinker with it further on their installs of WOTR. The package, while it eliminates blue triangles and noticeably improves fps over stock - is not the "magic bullet" that such tweaks, and previously Panama Red's, have been able to do in WOFF. Distance textures are indeed slightly more fuzzy with the tuner package for WOTR than if WOTR is run stock - so it's a personal choice for everyone. It might be possible to get even more fps out of WOTR but textures would then have to be blurred some more. I've tried to go for a compromise with this package - since, when run in stock form, my fps are consistently in the 40s, both in cockpit and outside views, in WOTR.
In terms of mega-stutters, I doubt I can help with that - I'm no magician.
Although I recommend, for those tweaking the preload.xml file in WOTR, to perhaps include several sounds there as well, towards the bottom of the file - since that may help with more noticeable stutters, such as when guns are being used for the first time, etc.
Try including the following entries at the bottom of the preload.xml file already included with my WOTR tuner package, if interested in testing on your rigs. I'm currently testing with these additions and noticed a slight improvement when firing the Browning 303s for the first time, when a dogfight begins.
Perhaps a placebo effect but worth a try.
