Weird FPS problems with NVidia cards

Post by Franc[e]sco »

Hey guys, so I've been developing a prototype of my first love game and I ran into fps issues on NVidia cards. I sent my game to friends to see if it ran fine on windows (I'm on linux) it runs fine for most of them, but some people wiith NVidia cards had some fps issues.

Let me exaplain the problem. Normally, my game gets 60+ fps (up to 1k)
On the gfx 260 and on the geforce 5500 it gets like 2-4 fps even on extremely good computers (like gfx 260 + i7 CPU) and I have no idea why. Also, the guy with the geforce 5500 can run Minecraft just fine (which also uses opengl). Could it be some issue with how love handles opengl or something?

Here's the prototype of my game --> Download
(The loading might take a few seconds because the maps are randomly generated)

I would test this for you since I have an NVIDIA card and a decent CPU but you only posted a Windows binary, which I cannot run. :(

EDIT: I tried renaming the file to a .love and it worked. I get a constant 60fps.

It runs at a solid 60 FPS for me. Nice procedural caves, but you should really make the Esc button give a menu, or at least close the game.

Win7 Pro x64
nVidia GTS 260
AMD Athlon x2 6000+
4 gigs of RAM

Since I have the same card and OS as your friend with the problem, I don't think either of those is to blame. Ensure your friend has the latest drivers, and doesn't have any infections slowing their computer down.

yeah, it was a very early prototype, I'll have a playable prototype released soon. Anyways, I'm quite sure at least one of my friends has the latest drivers because he can run stuff like crysis just fine with decent fps. It's a pretty random and weird issue :S

Ok here's more info on the problem.

Yesterday the game was working fine on a nvidia card. Today it randomly started giving the same problem for no reason and I can't figure out why the problem randomly appears o_0

Sounds like you may have a mandelbug in your code somewhere, which takes up a massive amount of resources when triggered.

Flat 60 almost all the time on a nVidia 560Ti.
