I don't see the problem with your hardware you not really posted a full hardware list but your PC might be old in age but its not really that old in spec it really still fits the bull for these kind of us, I really don't know much about the FPS's for love but if another system works ok for you and love does not maybe its just something coded different.

The framerate drop could be partly caused by the fact that when you were using SDL, you didn't have to manage a scripting language (Lua) which isn't an incredibly fast task, but Love does.

Before we can really give any performance tips that are relavent, could you post the code you're using?

There are always tricks to improve your FPS, depending on what you're doing. The tradeoff of using pure Lua to make games is that it's not as fast as the lower-level alternatives, but some simple changes to code can sometimes result in dramatic performance increases. Compiling LÖVE with LuaJIT can also help a lot, if you're doing a lot of pure-lua calculations/iterations. :)

If you ask me, the word Pentium is the problem these days. It's all about the Core2Duo's or the i3, i5 and i7's now. They're so much faster.

3GHz Pentium ~= 2GHz Core2Duo interestingly (And they laughed at the Megahertz Myth back in the day. Now who's laughing!? It was all true! True, I tells ya! The Megahertz Myth was real!!! *maniacal Spoony-as-Dr.-Insano-style laughter*)

this is simple sample test code.
only show background image and fly/moving object

this is my result
with backgorund: 16 FPS ( so slow )
without background: 110 FPS

why is FPS drop so much like thats?
any wrong from the code, or from my hardware?
there are any triks for this?

That code is fine, though I have to ask, why 1 * 0.9? Why not just 0.9?
