Bad performances with both catalyst and free driver

Hello,
With the  catalyst driver 15.20 and Xorg 1.16 my graphic card(hd 7870) is not used at her maximum for example in kerbal space program i have beetween 45% and 88% Gpu load but only in place like oceans normaly it don't exceed 75%, i have the same issue in war thunder,star conflict,robocraft but with unigine benchmark's (valley and heaven) it is good. I dont think it is normal . The cpu isn't overloaded it is a i5 3570.

  • MacPro with both Leopard and Tiger drives. Want to switch iTunes How

    I am running a MacPro with both Leopard and Tiger drives. I finally want to switch everything to Leopard and its drive. I have iTunes on the leopard drive but have never used it. How can I transfer my iTunes music, iPhone Apps etc. from the Tiger iTunes to the Leopard with the least amount of fuss?

    Hello hassiman,
    For additional information regarding moving the entire library from the 10.4 partition to the 10.5 partition, see this article:
    http://support.apple.com/kb/HT1449
    If your iTunes Library is substantial, you may want to consider backing it up to an external location as well:

  • External hard drive use with both Mac and Windows

    I know that you can't use an iPod (through iTunes) with both Mac and Windows, but can you still use it as an external hard drive with both operating systems?

    Yes, if the iPod is in Windows format. Mac OS X can read and write Windows formatted iPods, but Windows can't access Mac formatted disks unless special software is installed.

  • Can I mount my external hard drive which will be compatible with both Mac and Windows?

    Hello,
    Can I mount my external hard drive which will be compatible with both Mac and Windows? If yes, then please let me know, because I intend to use my hard drive for both Windows and Mac, without losing any file.

    Yes. By default, Mac OS X and Windows can read and write drives which are formatted as FAT32 or exFAT; NTFS drives aren't writable from Mac OS X without additional software.

  • APS on TP with both HDD and SSD

    Hi,
    I have a Thinkpad with both a hard disk drive and a solid state drive.
    How does Active Protection System work? Does it simply cut power to all drives in the system? Or does it explicitly tell disk drives to park the heads?
    I want APS to work on the HDD, but I don't want it to slow me down on the SSD. Can anyone confirm that this will be the case.
    Thanks! Please cite references, if possible.

    hey lucasreddinger,
    the APS works only with HDD unit. how it works is like this..
    as you know inside a HDD is circular platter that spins. when the unit is drop, the platter will shake and when it shakes, the APS will detect the movement and immediately halt the platter from spinning thus reducing damage to it.
    and because the SSD works like a flash drive and does not have any movable parts, APS won't work for it.

  • Lightroom 4 crashes when trying to open the slideshow module. I spent over three hours with both Adobe and Apple tech support and we know it is a permission issue but have not been able to get it solved.  It started with the last upgrade to 10.8

    Back up all data.
    This procedure will unlock all your user files (not system files) and reset their ownership and access-control lists to the default. If you've set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it.
    Step 1
    If you have more than one user account, and the one in question is not an administrator account, then temporarily promote it to administrator status in the Users & Groups preference pane. To do that, unlock the preference pane using the credentials of an administrator, check the box marked Allow user to administer this computer, then reboot. You can demote the problem account back to standard status when this step has been completed.
    Triple-click the following line to select it. Copy the selected text to the Clipboard (command-C):
    { sudo chflags -R nouchg,nouappnd ~ $TMPDIR.. ; sudo chown -Rh $UID:staff ~ $_ ; sudo chmod -R u+rwX ~ $_ ; chmod -R -N ~ $_ ; } 2> /dev/null
    Launch the Terminal application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
    Paste into the Terminal window (command-V). You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
    The command will take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear, then quit Terminal.
    Step 2 (optional)
    The first step should give you usable permissions in your home folder. This step will restore special attributes set by OS X on some user folders to protect them from unintended deletion or renaming. You can skip this step if you don't consider that protection to be necessary.
    Boot into Recovery by holding down the key combination command-R at startup. Release the keys when you see a gray screen with a spinning dial.
    When the OS X Utilities screen appears, select
    Utilities ▹ Terminal
    from the menu bar. A Terminal window will open.
    In the Terminal window, type this:
    resetpassword
    That's one word, all lower case, with no spaces. Then press return. A Reset Password window will open. You’re not  going to reset a password.
    Select your boot volume ("Macintosh HD," unless you gave it a different name) if not already selected.
    Select your username from the menu labeled Select the user account if not already selected.
    Under Reset Home Directory Permissions and ACLs, click the Reset button.
    Select
     ▹ Restart
    from the menu bar.

  • Sending emails with both body and attachment to multiple recipients

    I have a requirement to send email with body and attachment to multiple recipients.
    Body of the email is a standard text. It is a proxy-to-mail scenario.
    Here is what I've done: (I'm using PI 7.11)
    One mapping from Source to Target structure (format of the attachment text file)
    Second mapping from Target Structure to Mail Package format.
    In the second mapping I'm concatenating the output of first step into "Content" of the Mail Package.
    "XIPAYLOAD" is the message protocol used.
    The "Keep attachments" option in the Mail adapter allows only to send "Content" as attachment or as body of the email.
    How to send an email with both content and text?
    The other problem is even with using ASMA, I can't send email to multiple recipients. I can only do CC and TO for 1 person each - a total of 2. Although I can resolve this by creating mailing lists, it is better if this can be addressed in PI.
    Thanks for any input you can provide!

    Thank you for your response Mikael.
    For the first question, I was able to find the solution in the following blog:
    XI Mail Adapter : Dynamically building attachment and message body content using a simple UDF
    (I just needed to search with the right set of key words )
    The key is to set the "Content Encoding" as "None" in the mail adapter. If this is not done, the mail will be sent with an attachment - untitled.bin containing both the mail body and the attachment text. Also, don't forget to check the "Keep Attachments" checkbox in the mail adapter.
    Multiple recipients could be added by separating the email IDs with a Comma. I have used ASMA to set the recipients.

  • Cisco ISE with both internal and External RADIUS Server

    Hi
    I have ISE 1.2 , I configured it as management monitor and PSN and it work fine
    I would like to know if I can integrate an external radius server and work with both internal and External RADIUS Server simultanously
    So some computer (groupe_A in active directory ) will continu to made radius authentication on the ISE internal radius and other computer (groupe_B in active directory) will made radius authentication on an external radius server
    I will like to know if it is possible to configure it and how I can do it ?
    Thanks in advance for your help
    Regards
    Blaise

    Cisco ISE can function both as a RADIUS server and as a RADIUS proxy server. When it acts as a proxy server, Cisco ISE receives authentication and accounting requests from the network access server (NAS) and forwards them to the external RADIUS server. Cisco ISE accepts the results of the requests and returns them to the NAS.
    Cisco ISE can simultaneously act as a proxy server to multiple external RADIUS servers. You can use the external RADIUS servers that you configure here in RADIUS server sequences. The External RADIUS Server page lists all the external RADIUS servers that you have defined in Cisco ISE. You can use the filter option to search for specific RADIUS servers based on the name or description, or both. In both simple and rule-based authentication policies, you can use the RADIUS server sequences to proxy the requests to a RADIUS server.
    The RADIUS server sequence strips the domain name from the RADIUS-Username attribute for RADIUS authentications. This domain stripping is not applicable for EAP authentications, which use the EAP-Identity attribute. The RADIUS proxy server obtains the username from the RADIUS-Username attribute and strips it from the character that you specify when you configure the RADIUS server sequence. For EAP authentications, the RADIUS proxy server obtains the username from the EAP-Identity attribute. EAP authentications that use the RADIUS server sequence will succeed only if the EAP-Identity and RADIUS-Username values are the same.

  • How can I hook up an epson scanner (2480/2580) via USB/Firewire hub- APEBS and be able to operate the scanner with both laptop and desktop computer?

    My Artisan50 works in this configuration currently!

    You can't scan to a device connected to the base station's USB port. Devices other than computers with both USB and FireWire ports don't provide any crossover between the technologies unless specifically noted in their description.

    thank you roger. i have attempted to connect my mbp now 3 times (all different ways with different cables purchased) but unfortunately no success. i understand that with me having an older mbp it can be a challenge. i have found this page http://www.wikihow.com/Connect-a-Macbook-to-a-TV but with my unsuccessful history, i have become skeptical. i will try your suggestion and let you know. thank you again.

  • My PC crashed with both CS6 and Lightroom 4. .

    My PC crashed with both CS6 and Lightroom 4. . .I purchased a Mac Pro.  Can I download the Mac versions of both programs and use my currenct serial numbers?

    You can with Lightroom, but not (as far as I know) with Photoshop. You ought to get in touch with Adobe's customer service people and see if you can "sidegrade" to Mac for a relatively small fee.
