So using the RX480 and doing some tests, on Nvidia games like Wow, there really is a performance deficit even compared to a Nvidia 780 when roaming around the world mostly to do with view distance, I am guessing the geometry processing on Nvidia is still better in this regards.
Also why is there no in built dynamic V sync support like adaptive Vsync.
However my biggest gripe right now is that the driver and I am on AMDs latest driver from a few days ago is constantly crashing on the desktop, this makes it annoying when trying to adjust settings in the drivers but need to restart the computer in order to gain access.
Using windows 10 64 bit and using a 21:9 2560x1080 monitor if this helps, also on a 5820K - MSI X99a sli plus board.
Even when leaving stock settings on the driver it still crashes and undervolted it as well, same thing, does this happen to anyone else?
Another game that seems to be having massive issues is the secret world, just loading into the game and I am instantly at 20FPS, even lowered all settings to low, it doesn't shift.
I have played the secret world back on my 7970 ages ago and that was fine and was running fine on the Nvidia 780, just thought I would give this as feed back to AMDMATT.
*Update, tried the secret world again in DX9 mode, this resolves the massive FPS drop, anyone have any idea why the DX11 mode is negatively affecting the RX480 this much for this game?
*Update 2 - noticed that with WoW specifically, once I alt tab and tab back into the game, the performance is pretty smooth, its on the initial load up into the world that has severe FPS issues, also back to the Crimson driver crash;
On boot up, I can easily go into wattman and make my adjustments as I see fit, however once I play any game and then exit the game and want to go back into Wattman, the whole driver crashes, the annoying thing once I reboot the computer in order to access the driver, all my wattman adjustments were reset to default however all my stresstests show stability.
I only get the driver crash if I ever need to go back into the driver after playing any game, though the software I have used mostly included firestrike, WoW, FF14 and witcher 3 so far, every time I exit those games and try to load crimson drivers, the drivers just crash/stop, going into other games has no issues.
