I'd like to ask how well your 386 is running Doom first version and compared it to the Cyrix 486DLC with the cache enabled. For me I found the 486DLC permit to set the window to full screen with the health bar and still is smooth, but in low details. No way in high details. I got a 486DLC and 16Mb of fast 60ns ram plus the 256Kbyte of L2 and a Cirrus GD5429 ISA.
With the 386DX-40 I could never set full screen because it was already at its limit at 70% of screen window, low detail.
What about your experience with it?
