Hello,
I just upgraded to the newly released Crossover Games 7.0.0 and decided it was worth testing HL2DM again, which I haven't played in some time. I was quite pleased! At a medium resolution of 1344 x 840 with video settings at the recommended levels, framerates held between 20-60. In intense fighting, they dipped to 20, but did not seem to go any lower. I was able to chase people down with the crowbar and managed to get quite a few kills in this silly way, attesting to the stability of the game's performance in Crossover. Inbound voice chat also seemed to be working perfectly, though I did not try transmitting.
Excellently done! I am very happy, and this will be my second Windows game, after The Ship, that I will play exclusively in OS X via Crossover.
I would say the game runs well enough to warrant giving it a "Gold" medal, and have rated it accordingly!
Regards,
Brighid
P.S.
I am using Mac OS X 10.4.11 on an Intel iMac (Early 2006) with a 2GHz Intel Core Duo processor, 2GB of RAM, and an ATI Radeon X1600 video card with 256MB VRAM.
