Other things to try:
-Dprism.verbose=true (output should show the following options
-Dglass.win.uiScale=1.0 (disables HiDPI)
-Dprism.order=sw (disables HW acceleration)
-Dprism.maxTextureSize=8192 (mentioned before - increases max texture
-Dprism.maxvram=2G (increases maximum texture pool to 2GB)
-Dprism.targetvram=2G (combined with maxvram, increases initial
pool to 2GB)
