Can you be more specific?
What/where is laggy?
- the battlescape units, both mine and enemy, are moving with a significant lose in the speed. That doesn't fully cure with ajusting the speed via the sliders in the options menu.
- the HWP in the battle moves antsy with a little delay beforу each next square;
- the projectile speed is much slower for the same slider position in the options menu;
- the global pop-ups are emerging with 1 -1,5 sec animation, versus the 0,2 sec animation previously;
- in some maps with 50+ enemies there were little lags aleady. But now they are significant - all the same symptoms + 50-100% time consuming enemy turn.
I already had it mentioned regarding the X-Piratez issue. J5 was perfect in terms of processability, HWP's didn't affect the overall speed. J7 added the lags into the battlescape regarding the HWP's in the battle and giant maps. In J9 I observed the same problems, so decided to avoid certain missions (Mystic Tower) and overall HWP's employment.
Note that I play on ultrabook, not the desktop, but still it has the SSD, nice processor and separate videocard.
