I wouldn't know about issues. I can only say as much as those games i've tried have no issues so far. On the other hand, i've been playing Settlers, K-240, and Chaos engine. The complete library of games are a lot larger then this, so issues may be waiting to show up.
A positive effect have been noted tho. K-240 is a fair bit faster, game-play is a lot less about waiting, and more about "the game". It means it's harder to target the small spaceships to give them orders, but i always had the habit of building a hangar on every asteroid anyway, so for me it works out well.
All i can say is that this is the first i've heard about faster accelerators being "bad" for games.
