+LostCat Subscriber² Share Posted January 27 I too am horribly concerned about 40 year old display interfaces and 18 year old framework performance. 1 Share Link to post Share on other sites
+virtorio MVC Share Posted January 27 I'd like to see a similar test, but using a pure Win32 app (not a WinForms app). Link to post Share on other sites

The 30 year old display interface and 18 year old framework is used in a huge, huge number of apps - Win32 native code C++ apps as well as WinForms apps. Technically, some parts of Windows, some technologies are even older than 30 years. Do you refuse to use them and use "only" the newer bits e.g. exclusively apps or OS UI bits which use Direct2D and DirectWrite? 😆 Link to post Share on other sites

No. Do I care about how fast they draw virtually nothing? No. 1 Share Link to post Share on other sites
neufuse Veteran Share Posted January 27 so me a test on real hardware not in a VM, yeah VM testing is good but it puts another layer of complexity there, maybe the VM graphics implementation is causing issues? who knows 1 Share Link to post Share on other sites

I’ve never seen 1:1 graphics performance in a VM vs bare metal either. Edited January 27 by adrynalyne Link to post Share on other sites
MS Bob 10 Author Share Posted January 27 Yeah that's true. Slow performance in a VM is always a possibility. However that Twitter user says he tried it on physical hardware as well. Update: Second test: Third test: Finally he posted the test itself for you to test it on your hardware if you have different versions installed in multi-boot configuration on the same hardware: https://github.com/ADeltaX/REGDI/ Link to post Share on other sites
neufuse Veteran Share Posted January 27 I can't reproduce this on pure hardware using, using the provided code there is barely any difference between the original windows 10 version and the current 20h2 build that is publicly released on the same hardware and using latest video card drivers difference is within 1% Link to post Share on other sites
