To get long view distances with statics in them, MGE XE requires you bake the statics into distant terrain files before running the game. When it does this, it makes a bunch of optimisations, such as skipping smaller meshes and combining several meshes into one (Morrowind's meshes tend to be less l...

Figured I'd fire up Morrowind, now that I've moved on from a shitty i3 350 laptop with an Intel HD 2000 that needed a 64x64 texture pack for Morrowind at lowest settings, to a spiffy i5 4300m with an Intel HD 4600. Things seem to work, but I noticed that my gamepad is not supported that well. The Op...

Are you able to take advantage of batching and instancing with the generated objects? Having the option to batch the generated objects would be great for performance. Ideally OpenMW would implement a robust batching method that takes the best of both dynamic batching and static batching, but AFAIK b...

Deferred Shading is not as specific in use as just for when there are many small lights. With DS, draw calls concerning lights are only submitted for as many objects that are being affected by a given light. So if you have five lights in the scene, of 300 unlit objects with 30 objects being affected...

Damn it! I just bought fx-9590 :| It runs at 4.7 Ghz, with turbo 5Ghz Will OpenMW 0.43 not work faster with it? Are you using an AMD GPU? OpenGL's draw calls are slow as all hell on AMD's driver unfortunately. If you are using an AMD GPU, give this benchmark a run, to get an idea on how the FX 9590...

@MajinCry, I don't think the batching method is really our problem (any method is more or less fine I think), the problem is what can we batch in the first place when this gets massively complicated by Morrowind's files which: * are affected by many (some moving) lights, * move or disable objects u...

Has the OpenMW team ever made contact with Boris Vorontsov previously? I said it before, but he'd be a great contact to get info on optimizing the renderer side of things.

With OpenGL 4.3 you can use glMultiDrawArraysIndirect/glMultiDrawElementsIndirect to achieve what MajinCry is suggesting. How much of a performance increase you'll get will of course depend on the driver implementation of it. I do think it would be best for the devs to make contact with Boris Voron...

But from what I'm seeing in this thread, the Draw thread seems to be the bottleneck for most people, and I don't have many ideas for that. It's possible that opting for Vertex Array Objects instead of display lists (to be released with OSG 3.6) would help with AMD GPU's (I know it doesn't help for ...

Asking for more robust graphics is a bit wanky, considering the antiquated visuals the game ships with, but having the game be parallelized can only be a good thing. Let's have the AI being processed in the background, with all of yer cores workin' on it. Why have that? So we can have buttloads of N...
