Please send all questions and comments related to this gallery to Danil Gridasov.
Testbed
Games are tested on Pentium 4 3.4 GHz (800 MHz FSB) PC with ASUS P4C800-E (i875P) motherboard and 1024 MB PC3200 3200.
The test is run only under Windows XP Service Pack 2 and DirectX 9c.
The following cards were used in making of this material:
- ATI RADEON 9200
- ATI Radeon 9600
- ATI Radeon 9800 Pro
- ATI Radeon X800 Pro
- NVIDIA GeForce4 Ti4600
- NVIDIA GeForce FX 5200
- NVIDIA GeForce FX 5700 Ultra
- NVIDIA GeForce FX 5900
- NVIDIA GeForce 6800 Ultra
The latest changes are marked light-red.
Games are tested with the latest reference drivers (61.77 for NVIDIA GPUs, 4.9 for ATI GPUs) coupled with the latest patches. When a bug is found, it's tested on the next reference betas. Exceptions prove the rule :-)
Some bugs may occur in our testbed only. So if you don't witness them, or witness bugs previously unwitnessed :), please email us providing most details about your PC configuration (processor, chipset, graphics card and drivers, OS, DirectX version, game version). Besides, you can send us a screenshot not more than 200KB in size ('cause we have to pay for traffic :-)
News
Removed a number of bug descriptions fixed in August issue.
The following drivers were released in October:
NVIDIA:
ForceWare 66.77 and 66.81, beta version of NVIDIA reference driver. This month, instead of leakages, betas were published by NVIDIA at its website and FTP, so we decided to examine ForceWare 66.81 with all our cards.
The following patches were released in October for games in our list:
Games
- Beyond Good & Evil v1.01
- Chaser v1.50
- Command & Conquer Generals v1.7 / Zero Hour v1.02
- Delta Force Black Hawk Dawn Team Sabre v1.50

66.81 |
When v-sync is forced off in driver, triangles start to blink and disappear ingame. |
- |
This doesn't happen if you force v-sync on or leave it being controlled by application. |

When anisotropy is enabled, a
visible line of noisy textures appears in front of the camera. |
|
This is either a driver bug,
or result of texture filtering optimization. This doesn't occur
when Anisotropy is forced from driver. |

Again we could see onscreen garbage
when AA was forced from driver and postprocessing was on screen. |
|
Use older drivers like 61.77. |

Incorrect water rendering at Ultra High and High detail levels. |

Fixed in Patch 1.3. |
GeForce FX 5200 |
66.81 |
After Patch 1.3 GFFX5200 introduced lots of shaders 2.0+ bugs. |
|
For now just disable all shaders 2.0 effects. |

Clear banding on light source reflections. |
|
A result of extensive game optimizations for a number of ForceWare versions. 66.xx + patch 1.2 produced normal quality.

GeForce FX 5700 Ultra
GeForce FX 5900 |
66.81 |
Patch 1.3 made GFFX draw CryVision invisibility shader in another way. |
|
Might not be a bug, but an official GFFX optimization.

All versions |
Thermal camouflage effect with GeForce FX cards becomes like that on Radeons, if you make Halo think it runs on Radeon 9600 (with 3DAnalyser). It's interesting that frame rate doesn't reduce after that at all.
(Screenshots obtained with GFFX5900 with Radeon 9800 Pro DeviceID are to the right.) |
|
It seems like very aggressive optimization for GeForce FX. We doubt it will be fixed, even despite the arrival of Geforce 6800.
(Screenshots obtained with GFFX5900 with native DeviceID are to the right.) |

No shadows in shadow buffers mode. |

Mentioned in release notes of ForceWare 61.77. According to NVIDIA, it's an application bug.
