[carry-over] help opengl performance

[Nfaug]

so im posting this here as well because it seems to have turned into a support thread rather than a hardware question thread.

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
so using my current hardware i was able to get stable 30fps using direct3d with Windows 7, however on windows with the newest development builds id get about 15'ish stable with opengl.   I know that direct3d isnt supported on linux, so im curious if now that i got linux back on my system, with it being more light-weight, will the newest dev builds get a stable 30 fps with my current hardware?




Operating System: Linux Mint 17.1 KDE
Processor/CPU: Amd Phenom II X4 940 Black Edition Deneb Quad-Core 3.0GHz
Video Card/GPU: Nvidia GeForce GTX 460
Memory/RAM: 4gb G.SKILL



Edit : so it seems using the master branch version from ppa:glennric/dolphin-emu that i can get 60 fps in intros/videos and 30 fps in game with twilight princess + enhancements, but on spyro im bouncing between 30's and 40's fps with videos in spyro a new beginning with like 15 - 20 fps in game.

what is wrong with the opengl backend?
also, for some reason i can not switch games, i can run one game and play it, but if i choose to play a different game after i close it, dolphin closes. so i have to exit one game, exit dolphin, than open dolphin again to play another game.

The second thing you mentioned is an SDL bug. As for the OpenGL stuff... your processor isn't weak, but it isn't strong, and Twilight Princess, at least with the Patch, isn't that bad.

There are a ton of spyro games, but I do know at least one or two of them are variable framerate and actually run at 20 fps in many areas. Assuming you're not playing that one, I do think the Spyro game are fairly demanding at higher internal resolutions.

https://wiki.dolphin-emu.org/index.php?title=G6SE7D is the spyro game, also the sdl bug refers to the crashing/having to reopen correct?

i had thought my processor was more than enough for dolphin, guess i was wrong :/.

also, ive tried turning off the enhancements but it has no impact on the bad state of performance i get from the spyro game.

Are you using the proprietary video driver or the opensource driver?

i am using the proprietary drivers, however i did turn off all enhancements (again not expecting a difference since it didnt help last time) saved them and exited dolphin. did a full system shutdown and than started it up and loaded dolphin and that has fixed the performance problems with it, i have not a clue why and would love an opinion from a mod or something as to why something so ... odd fixed it.

Please don't refer to games by their game codes. I will forgive you since you linked to the game ( ), but if you hadn't, it's a pain to try and figure out what game you're talking about with just the game ID and not the name.

You may have had something running in the background that wasn't properly shut down when you were done with it that was interfering?

While your CPU is not a weak CPU, AMD CPUs have weak single-core speeds, instead relying on lots of cores to spread out the work. Dolphin is only a dual-core program, so the faster your 2 cores are, the faster Dolphin is, which AMD chips aren't very fond of. You can always overclock your CPU if you can for a speed boost.
