Hash rate problem

[wing_hk]

I am new here and also new for mining. I can just post here so hope someone can help me 

I just begin mining BTC,LTC and some other coins with 5770 card.

I found when mining BTC/LTC my hash rate is around 200KH/s (using cgminer) and the rate is 8xx-1,2xx KH/s when mining Applecoin (using their own miner, interface similar to cgminer). However when I set environment variable GPU_MAX_ALLOC_PERCENT = 100, the rate just drop to 50KH/s.

There's no any hardware settings in my command line. I'd like to know are my rates normal and does different coins have different rate due to their own algorithm or what?

Thanks

Applecoin? WTF. Don't do whatever you are getting scammed into doing.

GPU mining for Bitcoin is long gone, you won't be able to mine enough bitcoin to even make enough to withdraw from a pool.

Here is a litecoin hardware table, the settings and software for 5770s are there along with performance:
