Re: Distant lands and frozen cliffracers

It would be nice to see a number of "fade" options like in Oblivion and Skyrim for aesthetic and performance reasons. Example from Skyrim

Re: Physics lag issues, syncing issues, mp

OpenMW is currently programmed to update physics in fixed time steps, exactly 60 times a second. This ensures maximum stability and accuracy in the physics simulation no matter what the player's frame rate is. However, if the PC can't maintain 60fps during gameplay (due to weaker hardware, performan...

Re: CPU and Single Core Implications

On the other screens where you have all F3 panels enabled, it's understandable the FPS takes a hit because all objects in the scene (even non-visible ones) are being counted. This appears to happen between Update and Cull and is not registered on the profiling graph. Understood, that makes sense. I...

Re: CPU and Single Core Implications

But still, there seems to be some strange idle time in between the draw phases on that one picture. It's even more apparent when looking up . To be clear, vsync and frame limiter is off, as you can see when I enter a nearby interior . From what I can tell so far, the oddity only manifests outdoors....

Re: CPU and Single Core Implications

(is it not fixed there?). I'm using Ace's nightly build 7245b251e8 which is fairly recent, so probably not. The framelimiting can do weird things because they put the CPU to sleep and CPUs don't like to wake up at a precise time, they like to switch to another thread and get back when they're finis...

Re: CPU and Single Core Implications

The scene graph looks fine. I'm not going to take too close of a look though because the version of OSG used to generate file has that bug causing it to not indent lines which are really a pain to read. Can a fix be submitted and merged upstream it if makes the graphs easier to review? For another ...

Re: Distant lands and frozen cliffracers

Thanks to the way Morrowind handles the camera and player visibility, you can leave cell and view distance at default and still see this phenomenon quite easily; it's fairly common to spy frozen Cliff Racers in the corner of the screen. I agree this will need to be addressed sooner or later if dista...

Re: CPU and Single Core Implications

Decided to test in a different region. This time around, it's a small win for the performance patch. I picked the large tree near the center of the image for the scene graph. Maybe this will help diagnose the Bitter Coast example.

Re: CPU and Single Core Implications

Certainly, here you are. I clicked on the secondmost tree on the right in the image to get this. https://pastebin.com/aFw0kNvX And this is with the performance mod disabled: https://pastebin.com/5GFJd0LY Looking at the amount of depth sorting that needs to happen in the latter, the results of the pr...

Re: CPU and Single Core Implications

Performance is slightly worse with the performance patch, at least on some cases. Not sure why. Only difference between these two screenshots is toggling the patch on and off in openmw.cfg; you can tell it's active or not by the transparency of the leaves. (viewing distance is set to 666666 in both,...
