Call of Duty: Modern Warfare 2 Forum

I only recently made the switch from Windows to Ubuntu. I would have made this switch many years ago except for the fact that I love playing games, and of course Ubuntu and Linux in general have a bad reputation for gaming. After reading the forums and viewing the screen shots I tried using CrossOver Games Linux to install Steam and play Call of Duty: Modern Warfare 2. To say the game is unplayable is to say the least indeed. Whether all graphics settings were turned up or down the game was unplayable and very unresponsive. In Windows I can turn all settings up to medium and not have the frame rate drop below 60 fps. I expected lower in Ubuntu but to drop to 10 - 15 fps with all settings at their lowest is atrocious. I have gone through the forums and tip and tricks pages and tried everything there and could not the game to run any better (it is of course possible I missed something, if I have sorry in advance). FYI I am running Ubuntu 10.10 64 Bit with an ATI 5650 1GB VGA Card and Core i5 430 M CPU. Am using the trial of CrossOver games I downloaded a few days ago. Would love some feedback or assistance with this, I have a very large game library and after having tasted Ubuntu I really dont want to go back to the caveman days.

Also forgot to mention I am running the propriety driver for the ATI 5650 and have gone through all the settings there as well.

Hello,

I'm not entirely sure about the current situation but from past experience, ATI cards and drivers perform extremely badly under Linux. In fact, that's the main reason I switched my PC to all NVIDIA cards when I upgraded. (ATI drivers were constantly lagging behind in feature support and performance.) I'm hearing that this has improved with the more recent ATI cards, but can't vouch for it.

One thing you can try and check is to make sure that 'DRI' is enabled and working. Run glxinfo or fglrxinfo and look for a line that says 'direct rendering: Yes'. If this says 'no', you don't have hardware acceleration and everything is being done in software. You'll need to check the driver installation in that case.

For what it's worth, CoD6:MW2 runs pretty badly on MacBook Pro with Nvidia 9600 graphics as well, under Cider. If you push the settings above the stock ones, you'll either get glitches or game will crash. Lowering the screen rez to 800x500 may yield a much smoother framerate, sadly it doesn't stop hiccups from happening, even as you're just standing and looking around... This, at just the training level. That being said, I don't imagine anyone having much fun playing this on OS X. Perhaps Ubuntu is different, I wouldn't know.

Well, I'm getting relatively good performance on linux (fedora), 3GHz core 2, nvidia 260gtx, Resolution: 1680x1050, Shadows: No, Specular Map: Yes, Depth of Field: Yes, Soften Smoke Edges: No, Ragdoll: Yes, Bullet Impacts: Yes, Texture Quality: Manual (High, Normal, Normal). It's usually smooth, but in some places a bit laggy, but still playable (setting everything to low fixes that).
