Sergio Posted October 15, 2018 Share Posted October 15, 2018 "Late Start" on CPU graph with Vive Wireless Adapter:https://cdn.discordapp.com/attachments/351354713628737546/501444361431678976/unknown.png Link to comment Share on other sites More sharing options...
Sergio Posted October 15, 2018 Author Share Posted October 15, 2018 i7-8700K/1080Ti/Vive Pro CPU Usage same as with wired connection. But performance is worse with wireless connection. Link to comment Share on other sites More sharing options...
Synthesis Posted October 15, 2018 Share Posted October 15, 2018 Could you give me the lay out of where on the mainboard the PCIe card for the wireless adapter is slotted?Thanks, -John C Link to comment Share on other sites More sharing options...
Sergio Posted October 15, 2018 Author Share Posted October 15, 2018 I tried all ports. Absolutely all. No difference. I found a dependency, the more supersampling, the more likely to see the "Late Start", even if there is a headroom of gpu and cpu. Link to comment Share on other sites More sharing options...
Sergio Posted October 15, 2018 Author Share Posted October 15, 2018 with 100% render resolution there is practically no "Late Start" but with 150%... 200%.... it's appear more and more frequently... even if game easily can handle 300% render resolution.

Maribel_Hearn Posted October 15, 2018 Share Posted October 15, 2018 The wireless adapter is too weak to process a super sampled scene. See my thread about it here: https://community.viveport.com/t5/Technical-Support/VIVE-Wireless-Adapter-and-Supersampling/m-p/23776#M9109 Link to comment Share on other sites More sharing options...
Sergio Posted October 15, 2018 Author Share Posted October 15, 2018 I think you do not understand how it works. Wireless adapter should work with image after supersampling process. It works with same size of image, any time, with any supersampling settings. Link to comment Share on other sites More sharing options...
Maribel_Hearn Posted October 15, 2018 Share Posted October 15, 2018 The wireless adapter compresses the output image from the GPU and then decompresses it after transmission. Even though the resolution it is working with is the same, the added detail from supersampling exceeds its processing ability to compress in a timely manner. If this or some variation of this was not the case, the wireless adapter would not have issues with supersampling. Link to comment Share on other sites More sharing options...

If this or some variation of this was not the case, the wireless adapter would not have issues with supersampling. The output image is the same size no matter of supersampling. HMD receive image that the same size no matter of supersampling and no metter it's used wired or wireless connection. Because supersampling proccess happening before image passes to HMD (and wireless adapter). The result of this process is image with size of HMD screens.

Sergio Posted October 16, 2018 Author Share Posted October 16, 2018 I also opened "issue" on Valve's GitHub page. https://github.com/ValveSoftware/openvr/issues/913 I think it's Steam VR or Vive wireless software issue. I really don't see any difference with any PCI-E port. With any settings in BIOS for PCI-E... with any Nvidia driver. With old or new BIOS firmware for MB.
