Honestly, its not a fault ssd, because other programs works just fine, i have Windows 7 ultimate 64 on it.... and yes latest microprogram on chip, the reason i write this was that i think Samsungs SSD controller are not universal, and for high level gaming better would be SandForce because this...
When i installed cs 1.6 on my ssd 840 evo i noticed crosshair delay.... it was a big disappointment. I think, because of huge marketing company by kingston ssd`s among pro gamers, sandforce controller may be real deal for gaming.... better than samsung`s one.
I play in cs 1.6 on quite high level, one of the amx admins on the server, and using this one for precision gaming:
before i used PX 100 Sennheiser, but these one`s are better for me, screenshot of equalizer:
