View Full Version : [Mac] Slow frame rate when hero come into the view

Hi there!

I just tried the game for the first time today going through the tutorial.

I first tried it on my MacBook Pro with Mac OS X 10.6.7 (previous generation with Core i7 processor, NVIDIA GeForce GT 330M graphics with 512 MB VRAM and 8 GB RAM) and I noticed that I could scroll around on the screen smoothly (at least 60 FPS) but as soon as the hero character game into the view the frame rate started to stutter. It seemed a bit unmotivated that the frame rate should drop that much just because of that.

I tried lowering the graphics settings a little, but it behaved the same. The slowdown also happens when viewing a fight that the AI controlled minions (whatever they're called). Is it some kind of particle effect that causes it?

Anyway, I tried on a different computer, a desktop tower with at Core i7 920 processor, 6 GB RAM and Radeon HD 4890 graphics card with 1 GB VRAM. Running the game in Windows on this machine was flawless on the highest settings. I also tried the game in Mac OS X on this machine (which I guess isn't supported since it's not a Mac, but Starcraft 2 and several other games run just as well as in Windows) and I got the same problem as on the MacBook Pro.

So, what gives? Is this the way the game currently behaves on the Mac or am I doing something wrong?

Ahh, I missed this:

”Refraction
Due to the graphics drivers and OpenGL impelementation under OS X, users should turn off the refraction video option in the Heroes of Newerth. This option, if enabled, will cause the OS X OpenGL renderer to have significant performance drops when rendering certain scenes (water, towers, and spell/item effects). This affects both NVIDIA and ATI/AMD graphics cards.”

Now it works fine.

Anyway, one can still wonder why it as to be like this i Mac OS X. I wonder if it behaves the same in Lion?
