Performance problem
Posted: Wed Oct 22, 2008 4:13 pm
After reading this post :
I have started to code with love on my personnal laptop computer (~4-5 years old, with nvidia gforce ...) I got a very good performance like more than 1000 FPS on a very simple love sample, and between 100-250 FPS with my actual game.
After that I have checked on 2 office computers (less than 2 years old).
1 (workstation) Dell optiplex 755 and 1 (laptop) Dell Latitude D620,
both have Intel Graphics Controller.
And both I got less than 100 FPS on sample and 2-3 FPS with my game !
Is it a bug or love need a "true" 3d accelerated chipset ?
Some technical details :
I'm starting to tell what I got.Tenoch wrote:Well, the "official" ubuntu deb of Löve works with Ubuntu on the Eee. (I run Ubuntu-eee, but i'm pretty sure it's really the same).
Unfortunately, perfs are terrible. I don't know the reason, but i suppose it has to do with the fact that Löve relies on OpenGL and hardware acceleration for everything. Almost all "real time" demos posted here have a FPS so low it becomes unplayable.
This is too bad since the Eee has a quite correct processor, and plays "pure" SDL games really fine.
Maybe we'd need a "SDL render" option in Löve, even if it would propose less features (like this really neat seamless rotation and zoom of sprites). But I don't know if it would need a lot of work or not. I think i reaad somewhere that Löve didn't even use SDL_Surface at all, so I guess it would need a lot of rewriting.
Too bad. For now I'm back to plain old SDL calls, and wrapping stuff in Lua...
