I know that assets are now pre-cached which is probably helping Runescape
I tried Dungeoneering for the first time in HTML5:
*Some wall objects in dungeoneering like the end dungeon ladder and some corners are too low down, leaving gaps in the walls.
*Bloom permanently on in dungeons? No shadows or water detail. Everything looks over-bright and de-coloured.
*High framerates (50+) at first with just one room, down lower (9-11) when looking back at entire revealed dungeon. Low draw distance only claws back 10 FPS.
*Smelting and herb cleaning interface slider doesn't work (but +/- buttons do). Smithing seems to be okay.
*I drop a large pile of Salve Eels, and when I start picking them up they seem to rotate on the spot. Bug or feature?
I can run the game (client and browser) with everything maxed and get 20-30 FPS even in the busiest of areas topping off at 45-50 in quiet areas. All while watching YouTube, running AV scans and numerous other tabs open in Chrome.
Sure, my computer is Buy Runescape Gold relatively old, but it's no slouch either. I tried the beta today after seeing the announcement in the hope that it had been optimised, but sadly I was mistaken and it still looks the same (bad if I'm honest; no where near the current Java equivalent).
