SU v8 uses an older OpenGL 3D display output stack which is less demanding than the OGL version of 2017+, sticking with it because of flaky graphics card drivers would stop further development of an enhanced and faster 3D display output (as e.g. an improved shadow with v2017) and is therefore surely no real choice. Having back the option to disable OGL in hardware as version 2016 (and older) could be an option, dunno how difficult to implement.
Bt why not simply drop ypur old/lame FirePro V4900 (2012) and upgrade your system to e.g. a recent GeForce GTX 1060 roughly 7 times faster starting from approx. 200 bucks?
Check space in case and req. wattage of PSU before buying.
