Have a look at... http://support.citrix.com/article/CTX781561 <http://support.citrix.com/article/CTX781561&searchID=13276050> &searchID=13276050 You need to make sure your color depth is in the equation..... 2 1024 x 768 16 bit color 3,145,728 Remember you need to set it for the highest resolution machine that you use. I haven't seen it cause any performance issues by giving it to much memory. (especially modern hardware) I believe it will only use the amount it needs to rather then allocate the full amount...I have it seen it cause more problems when resolution or color depth is degraded. Users don't like that much.

From the Help Screen in the CMC (we run MFXP) it gives the following formula: (color depth in bits per pixel / 8) * vertical resolution in pixels * horizontal resolution in pixels = memory required in bytes. Our users generally use, at the high end, 16bit color depth @ 1024x768 resolution. So that would be (2) * 768 * 1024 = 1,572,864 bytes required for graphics. The default looks to be 5625 for this setting, which is much larger than we appear to need. Why would you (I) need to increase that? Would it give me better video performance or just allow for huge graphics reolutions or multiple monitors? Would reducing this number give more memory back to the OS?

I am using the default setting for the farm of 5625 kilobytes. What are other people using for this? This is a XP farm.
