+//NOTE: Polygon Offset does nothing at the moment.

+#define TGL_FEATURE_POLYGON_STIPPLE 0
+//A stipple pattern is 128 bytes in size.
+#define TGL_POLYGON_STIPPLE_BYTES 128
+//A stipple pattern is 2^5 (32) bits wide.
+#define TGL_POLYGON_STIPPLE_POW2_WIDTH 5
+//The stipple pattern mask (the last bits of the screen coordinates used for indexing)
+//The default pattern is 32 bits wide and 32 bits tall, or 4 bytes per row and 32 tall, 4 * 32 = 128 bytes.
+#define TGL_POLYGON_STIPPLE_MASK_X 31

+./model -m monkey3.obj -count 27
+```
+
+Hovers around 55-62 fps at count 27.
+(I get the exact same performance figures with textures enabled)
+
+```
+./gears
+Low: 731 FPS
+High: 885 FPS
+Average: around 835
+```
+
+```
+./helloworld
+Low: 1178 FPS
+High: 1530 FPS
+Average: around 1380 FPS
+```
+
+```
+./texture
+Low: 476 FPS
+High: 547 FPS
+Average: around 510 FPS
+```
+#### With NO_DRAW_COLOR enabled, otherwise the same
+
+```
+./model -m monkey3.obj -count 24
+```
+
+Raising the count above 25 causes the count to unreliably stay above 50 FPS and never reach 60.
+
+```
+./texture
+Low: 467 FPS
+High: 592 FPS
+Average: around 570 FPS
+```
+Surprising that it actually runs faster
+
+```
+./gears
+Low: 804 FPS
+High: 917 FPS
+Average: around 842 FPS
