The problem seems to have been fixed, I don’t know if it was a graphics driver bug with Windows 10 Pro or AMD Graphics driver bug or something changed in Unreal Engine, but what I did was removed the graphics driver completely (which I usually just upgrade), and then re-installed the Crimson package from AMD and then in Unreal Engine I run the command t.MaxFPS to manually set the FPS to 60 FPS to lower it, on average it was around 120 FPS on up or about whatever I set it too which really is too high for light editor usage.
So far I haven’t had the problem since and I am using 4.12.5 now and that is running much better than the 4.9.2, 4.10.4, and 4.11.2 did, it has a very similar feeling to 4.9.2 and 4.10.4, it did happened again when using 4.12 early versions but hasn’t since update.
The machine I’m using for the main one uses an AMD APU and Gigabyte ATI HD 5770 1GB GDDR5 on Gigabyte motherboard.
I have a similar machine using a Intel Core 2 and it uses a near equivalent NVIDIA Galaxy GT220 1GB on Inspiron 530.
Also, in my tests I cannot run a compiled game from Unreal Engine Windows 64-Bit or Windows 32-Bit without severe performance issues on the NVIDIA card unless I compile and stream the game in HTML5 format/platform and run it from Firefox browser which seems to offer the best HTML5 WebGL performance, a popup notification comes up from Unreal Engine telling me that there are performance issues with the existing drivers and I must upgrade the drivers, when I attempt to upgrade using NVIDIA’s software and website I find the appropriate drivers are very hard to locate, and the software says that updated drivers may not be available for the card.
AMD continued upgrading their drivers and my ATI Graphics Card has much greater performance than the NVIDIA graphics card because they stopped doing updates and so the ATI card actually has and is using newer tech and the responsiveness is what you’d expect.
This makes it very difficult for me with the NVIDIA drivers no longer being updated and as result I know I’m gonna have to eventually get a new card for improved future VR and Vulkan development and will need to shift the ATI HD 5770 (so the previous computer maintains graphical performance) into the NVIDIA GT220 (which hasn’t been used much and lags out even with Substance Painter which also presents the GPU driver warning.) cards place and things like NVIDIA IRay and features in programs like Blender make use of GPU on NVIDIA cards and so pretty much means my next card has to be an NVIDIA, Blender usage still does great with the ATI card and Unreal Engine.
For now, the working development solution seems to be to run stuff like Unreal Engine, Substance Painter 2, Substance Designer 5.4, Bitmap2Material 3 1.3, Blender 2.77a, DAZ Studio 4.9 with IRay and anything else on the AMD APU and existing ATI card machine, and use DAZ Studio 4.9 with IRay and Blender 2.77a with NVIDIA GPU optimizations on the Intel Core 2 with NVIDIA card, the rendering for content authoring is a bit slower but it works, if NVIDIA ever did upgrade the drivers to keep the older hardware up to spec then I don’t think it’d be as much of a problem in the long run.
I’m thankful to Epic Games and AMD the latest Unreal Engine and older AMD hardware is still working and continues to be improved through software updates.
