Radeon GPU with switchable GPU suffers the same problem too.
Laggy mouse. Bad thing is, Radeon GPU does not run opengl. Good thing is, you can disable switchable GPU in bios. Disable the switchable GPU will solve the issue. |

QUOTE(gogo2 @ Nov 1 2010, 08:49 AM) huh? ATI not running opengl? now that's new thing I learn today.... Yes, ATI does not support opengl by default. seems like ATI and nVidia directX old driver is broken.... but is fixed in the latest driver... weird that both solve it at the same time   It requires separate driver. http://support.amd.com/us/kbarticles/Pages...iew-driver.aspx It is not the old directX problem. This is because changing to from "switchable" to "discrete" would solve the laggy problem. The driver works fine. It is generally the driver problem for the "switchable" and "optimus". |

QUOTE(gogo2 @ Nov 1 2010, 09:58 AM) I dun get what u meant... It is the "driver for optimus" problem, especially you can't turn on the discrete GPU. Optimus works fine for all other game with latest directx. Only Warcraft 3 with older directX not working. Also, by using openGL, switchable/optimus driver works fine... proof that no problem with Optimus/switchable. Only problem is with DirectX driver. If you search around the internet, even nVidia newer graphic card have mouse lag.. so definitely not Optimus issue. But a generally compatibality of DirectX 8 vs nVidia driver. You can't run in discrete mode with optimus. As I said, even Radeon with "switchable" suffers the same problem too. There is no problem for discrete GPU like GT330 to run Warcraft3. I never had laggy problem with GT330. It is a driver problem but it is not the directX problem. GT330/GT335 use the same set of driver. It is a "driver for optimus" problem. |

QUOTE(gogo2 @ Nov 1 2010, 10:28 AM) if cannot turn on discrete GPU, meaning it'll use i5-450 CPU which is more than enough for GT330 no mouse-lag issue. Warcraft 3. So mouse lag is not that it cannot turn on discrete GPU right?  I turned on the discrete GPU on my 3820TG & 4820TG and the mouse-lag issue was gone too. So, the possibility is current drivers do not run well in hybrid mode. They need better drivers. |
