Summary	02054: daytona, daytona93: "SEGA 3D: Max triangle limit exceeded" error appears after a few laps
Description	In video/model2.c the following if-clause is true after a while: if ( raster.tri_list_index >= MAX_TRIANGLES ) { fatalerror( "SEGA 3D: Max triangle limit exceeded\n" ); } Definition: #define MAX_TRIANGLES 32768 I get the message after about 2-3 laps on the beginner track (also in attract mode once). I have auto frame skip set to on. Once mame crashed after a few laps. When trying to find a regression version, I got these results: When trying daytona with 0.122u5, it popped up right after the announcer said 'go' on beginner track. The next try it crashed after 4 laps: ----------------------------------------------------- Exception at EIP=009B2A0B: ACCESS VIOLATION While attempting to read memory at 0A0ADBB0 ----------------------------------------------------- EAX=00106DC9 EBX=00000886 ECX=09EA0020 EDX=000836E4 ESI=00000BB2 EDI=0000005C EBP=0B2FFE80 ESP=0B2FFE30 Not sure if the following are related: 0.122 freezes mame at about the same moment (after 2-3 laps) 0.121 after 2-3 laps: ----------------------------------------------------- Exception at EIP=009A771B: ACCESS VIOLATION While attempting to read memory at 0A0DF5A0 ----------------------------------------------------- EAX=00167AC1 EBX=00000E92 ECX=09E10020 EDX=000B3D60 ESI=00000DA2 EDI=00000112 EBP=0B26FE80 ESP=0B26FE30 0.119u1 after 2-3 laps: ----------------------------------------------------- Exception at EIP=009B4FB3: ACCESS VIOLATION While attempting to read memory at 09F73EC0 ----------------------------------------------------- EAX=00101F50 EBX=000006C0 ECX=0000083A EDX=00080FA8 ESI=09D70020 EDI=00000020 EBP=0022F948 ESP=0022F620

No.01848 RansAckeR Tester Jul 30, 2008, 16:23	john_iv, did you use auto frame skip?

Game is still in GNW state, with graphical issues and running at about 30-50% against realtime, but no more crashes. I cannot accurately test the issue regarding AFS, as my machine runs the game at a perfect 100%. Leaving open for someone with an older/weaker machine to test with AFS working.
No.15868 MetalGod Senior Tester Dec 4, 2018, 21:41	The game runs a bit slow on my pc. I activated autoframeskip and played beginner race 3 times. No crashes or errors for me. I recorded one of my gameplays:
