# PCSX2 versions used:
Started with "Safest" preset;
Changes to the EE/FPU "Clamping mode" alone have no effect;
Changes to the EE/FPU "Round Mode" alone alter the severity of the bug;
The EE Interpreter is worse than the Recompiler.
# Plugins used:
GSdx AVX2 using the OpenGL, DX11 and DX9 renderers and software mode;
cvdvdGigaherz.
# Plugin settings: GSdx - CRC Hack Level "None"
# CPU: Intel® Core i5-4690K CPU @ 3.50GHz
# GPU: GeForce GTX 970 (Driver: NVIDIA 358.50)
# Description:
This was found in the Dakar 2 demo of the ops2m demo 33 disc.
With the "Safest" preset, a right trapezoid-shaped section of the race track in front of the player's car goes missing and we only see the skybox through it.
Some camera angles will make this go away.
Changing the EE/FPU rounding modes to something other than the default "Chop/Zero" will increase the severity of the bug - more stuff goes missing and camera angles will no longer make it go away, which leads me to believe this is a bug in pcsx2's EE implementation.
The following is a video of the bug, I also cycle through the different EE/FPU rounding modes:

Because I think this is EE rather than GS related, I didn't make a GS dump. What can I do to help the devs?
- pcsx2-v1.3.1-1270-g1c8f8a0-windows-x86 (latest dev build)
