But the Difference is probably anyway irrelevant for Trine 2, it doesnt use so much Physx anyway, Object Physics used in Trine 2 is probably very basic Stuff for Physx. I don't know exactly, but because the Files in the Trine 2 Directory are actually loaded and they are NVidia Files, i suppose they do read those Settings and switch CPU/GPU Physx. I also noticed that in the NVidia Control Panel if you set Auto for for CPU or GPU Physx it defaults to GPU now, also the Files anyway support both CPU and GPU Physx, but the Question now is that Setting relevant if they are used like in Trine 2 or not. So perhaps the GPU Drivers then pick the right one who knows. If you install the Physx Legacy Drivers Pack the only Thing that actually happen is that some new Directories are created in that Collection, that's all. There are also Versions from 2.6.xx - 2.8.x.x and up. Well, i also don't know exactly how they implemented it with the GPU Drivers, but i seen that they install alot of Revision along with the GPU Drivers and there seem to be alot different Physx Files specific for Apex and Gameworks. But who knows, maybe this is also more noticable on Plasma's like i used to play it, where the Refresh Delay is really small (0.00001ms response). Seems logical because Trine EE also has a Legacy Physx Driver Installer that also runs on the first start, while Trine 2 doesn't and has static 2.8.x.x Physx Files in the Game Directory, but the Phsyx Drivers from the GPU Drivers still seem to have some influence.īut i anyway came to the conclusion that the movable Object Stutter has nothing to do with the Physx Version, it's more like the fps for the Object is not synced with the fps the Game runs at, so no matter what, it will always stutter. But if all (legacy and the one from the GPU Driver) Physx Drivers are removed completely from the System by deinstalling them, Trine EE won't even start. Trine EE won't even start without Physx Drivers, Trine 2 does because the Files are in the Gamedirectory.Īlso for Trine 2 i was able to run the Game with up to 3-4 iterations newer Physx Files, but none helped for the movable Object stutter and with any newer Files the Game won't start anymore -> Black Screen -> Freeze and Task needed to terminate or CTD.īut Trine EE also works fine with the newest Physx Drivers from the newest GPU Drivers, no legacy Drivers needed but also works with the newest legacy Drivers, no stutter at all. Physx is statically linked and no GPU acceleration is used.īut for Trine EE it does for sure, i tried different Builds for Trine 2 but also exchanged the Files in the Gamedir.
