<p>Okay, I have two Radeon 5870's running in Crossfire mode.</p><p>I've noticed the following:</p><p>1) If I run them in Crossfire, and full screen I get kind of bad framerates. Usually playable unless I go into a raid or a guild hall with a lot of items.</p><p>2) If I run them in Crossfire but go instead to Windowed mode, I get fine framerates. I can raid in Windowed mode fine, go into any guild hall no matter how many items are placed fine, even my six room SQ home which has at least 100 pets fine, that place sometimes lags people worse then a tier 3 guild hall due to all the pets.</p><p>3) If I turn off Crossfire, I get fine framerates again, possibly even better then Crossfire in Windowed mode, regardless if I stay in full screen or windowed mode. But, the game will sometimes (but not always) lock up if I go from full screen to windowed mode with Crossfire off, or if I do the /browser command. Mind you, I am leaving both cards in my PC and leaving the Crossfire bridge cables connected, I'm just turning off Crossfire in the driver. I haven't tried running it with just one card installed in Full screen yet.</p><p>Anyway, it's kind of minor since I can do "2" and all is well, I mostly don't mind Windowed mode. But I was wondering if others have similar issues in general with Crossfire and specfically with 5870's? Forgive me if another thread mentions this, moderators feel free to merge my comment into that thread if one exists.</p><p>For the record, I've tried a release canidate driver that was posted on ATI/AMD's site on October 13th, Catalyst 9.10 drivers and Catalyst 9.11 beta. I'm currently using Catalyst 9.10, which is the current non-beta Radeon drivers and ATI at least claims they support the 5800 series cards.</p><p>Let me know if you'd like other system specs. I know it's not a power issue as an aside, I'm running a Tagan 1100 watt PSU, and made sure that each card was on a different 12 volt rail based on the manual in the PSU and the modular cables I hooked up.</p><p>Other system specs:</p><p>Gigabyte EX58-Extreme motherboard.</p><p>Intel Core i7 965 CPU. (CPU is OCed from 3ghz to 4ghz, has been for a year though with no issues)</p><p>6gb Corsair DDR1600 memory running tri channel (3 x 2gb sticks)</p><p>Sound is just the onboard Realtek audio chip, I'm hard of hearing so I almost never buy a sound card, I can't tell the difference anyway. <img src="/eq2/images/smilies/3b63d1616c5dfcf29f8a7a031aaa7cad.gif" border="0" /></p><p>OS Is Windows 7 Ultimate, 64 bit.</p><p>I know it's not a cooling issue, I have a Cooler Master Storm Sniper case..if you're not familiar with it, the thing has 3 200mm fans, one in the front, one in the side and one in the top, along with a 120mm fan going out the back. The CPU is cooled with a Thermalright TRUE 120 with one fan on it also, so it's handling the CPU and it's overclock fine, I've ran benchmarks, Memtest 86 and so forth in the past.</p><p>I guess if you need to know my hard drives and optical drives, feel free to ask.</p>
