I do recommend the following: search for MacGruber's "Benchmark" on the Hub, download it and all of its dependencies. Restart VaM, load the Benchmark scene, make sure to read and follow the instructions (make sure to "Apply Official UserPreferences" before running the official benchmark!), and then let it run (can be run in Desktop mode as well as in VR mode!). The benchmark takes about 10-15 minutes to run -- do
NOT touch your system while it's running the benchmark!
That should give you a good estimate on what your PC is able to accomplish. After the benchmark is complete, click on "Save Results", and you'll find your results in
Saves\PluginData\Benchmark
-- post your results in the "Benchmark Results Discussion" thread on the Hub -- see the "Overview" of the plugin for the link to that thread. There you can compare your system's result with others.
These are my results for "Desktop mode" -- not the best, but not the worst either:
// EDIT: After you've run the official benchmark, you can try to tweak your settings and then run the "Custom Benchmark" to see whether or not you've just improved the overall performance. Do not post results from custom benchmarks to the discussion thread I mentioned before, because only official results should be compared. And because there's always someone mentioning the "GiveMeFPS" plugin -- here's a custom benchmark of my system after installing that plugin and using the "recommended" settings: that's like an "improvement" of like 3-4%, which I personally think isn't worth it, you might get better results if you tweak your settings individually and for each scene separately.
