Fans of PhysX on 32 - mo CUDA are not quick to let go of the capability for theRTX 5090GPU . Gamers have become inventive by rigging the already expensive graphics card with additional , compatible GPUs to regain PhysX function on their play setup .
Nvidia late announced that it is halting support for the bequest GPU - accelerated purgative simulation technology , PhysX on newer graphics cards . This indicated that many popular older games would not be compatible with the RTX 5090 GPU and beyond in terms of detailed simulation and rendering . Without PhysX support , bequest games perform at significantly low frame rates and are n’t able to properly execute many corpuscle effects , including moving smoke , cloth , liquidity , and shattering deoxyephedrine .
Tom ’s Hardware antecedently noted it was potential to keep PhysX support run on a PC tend an RTX 50 serial GPU and beyond by mate it with an RTX 40 serial or honest-to-god graphics board , only tapping the latter component in to work on on the Nvidia control panel when necessary . This is exactly whatReddit user , jerubedodid – purchasing an RTX 3050 graphics card to pair with an RTX 5090 GPU . The enthusiast shared their resolution on the Nvidia assembly .
RTX 3050 pairing results
The gamer tested the two GPUs on several legacy biz , including Mafia II Classic , Batman Arkham , Borderlands 2 , Assassin ’s Creed IV : Black Flag , and Mirror ’s Edge to varied result . Overall , the run move over that the PhysX performance on the RTX 5090 GPU suffered without the help of the RTX 3050 .
The RTX 5090 ran on its own with significantly low frame rates . With Borderlands 2 , the drug user reported that PhysX would not run at all . Meanwhile , the RTX 5090 carry with support from the RTX 3050 , get much - elevated physical body pace and improved backup for effects . With Assassin ’s Creed IV : Black Flag , the gamer show the frame of reference rate were comparatively the same between the two setups , at roughly 62fps .
However , other games saw extreme divergence . The Redditor reported that Mirror ’s Edge saw a frame pace of 12fps without the RTX 3050 , with the plot pausing for 49 instant during a prospect of Methedrine shattering . In compare , the RTX 5090 and RTX 3050 brace had a frame charge per unit of 171fps .
No PhysX replacement
Notably , the RTX 5090 retails for approximately $ 2,000 , which is quite pricy for a compute component . The GPU is already in circumscribed quantity and high demand , making it even more inauspicious that Nvidia is plunder away long - appreciated functionalities from the artwork system . While buy an additional GPU to regain PhysX function is an interesting feat , it ’s not a move every enthusiast want to make when they expect their already expensive part to just work .
The reviewer at Digital Foundry podcast noted that without PhysX or a dedicated GPU , the RTX 5090 has essentially fall back half-witted compatibility when running older games . They added that without legacy support , the rendering that used to be carry by PhysX is now strike up by aspects of the CPU , which does not function as well . While they would have expected C.P.U. support to have catch up to the decades - old PhysX they do n’t find this to be the causa – bring in the retiring for this engineering all the more disappointing for many . to boot , the team take down there does n’t seem to be any PhysX alternate in the pipeline , suggest computer hardware rigging such as jerubedo ’s experiment may be fans ’ only option to keep back the high - end rendering they desire .
